Nice, the main purpose is calibration for HDR with the patterns , should be good coming from spears and munsil

Some correction, actually this serves more of an "evaluation" of the display after you have calibrated your HDR capable display using more pro calibration s/w like Calman, ChromaPure to name a few. So far, majority of these HDR 4K UHD "calibration" discs ONLY allows you to adjust basic parameters such as brightness, contrast, sharpness...there is no way you can use it to make any "on-the-fly" adjustments to say white balance, RGBCMY colors with accuracy w/o using those calibration s/w which I've just mentioned.

Only basic brightness  stuff etc ? I thought they had a more comprehensive test patterns for HDR , and u can use a meter to test these patterns like 10,20, 30% grayscale stuff, white balance ? No ? Just evaluation of what was calibrated ?

Those "test patterns" are for you to use with Calman and ChromaPure to help you with the calibration process...most if not all calibration s/w will have the built-in test pattern generator...So effectively, these patterns from Spears and Munsils as well as Masciola 4K HDR test patterns are provisioned as an "aid" to help you evaluate or "calibrate" in conjunction with the use of one of those calibration s/w to achieve optimized HDR results for your display.

Having say that....all is not lost as it still provides a good way to ensure shadow details (check through Brightness and Contrast levels) are properly tuned for 4K HDR content which imo is very crucial. The  Wide Color Gamuts (WCG) is a whole different beast which requires calibration s/w to get dE as low as possible and this requires a capable colorimeter to do it.

For evaluation... but
Here's an interesting question:

Here is my big question. I do not have any calibration equipment and don't see myself investing in any such thing anytime soon. Would I benefit from this disc at all if all I am going to do is adjust things by eye? I know that isn't the way to do it, but I assume it's better than nothing.

I have an LG C8 TV.
Short answer is a big YES without question.

Actually, the most useful patterns are for visual inspection.


This is for the 2nd edition http://spearsandmunsil.com/2nd-edition-articles/ but the principles and some of the patterns discussed are similar on the new UHD disc.

Stacey Spears and Don Munsil, creators of the acclaimed Spears & Munsil High Definition Benchmark series of test and calibration discs, have announced the release of the UHD HDR Benchmark, a 4K Blu-ray disc dedicated to the calibration and evaluation of 4K Ultra HD (UHD) displays that support high dynamic range (HDR).
Available on amazon.com for $39.95, the disc is said to provide a wealth of test and demonstration materials that enable professionals and amateur enthusiasts alike to evaluate TV performance, identify weak links in hardware and software, and dial in optimal settings.

“Every pattern has been rethought with high dynamic range (HDR) and Ultra HD in mind,” said co-creator Stacey Spears. “We believe this disc completely changes the game for test and evaluation discs, by making use of all of the features and range that HDR and wide-gamut standards can offer.”

HDR was designed with the future in mind. Instead of creating a standard based solely on the capabilities of existing displays, video-standards bodies designed HDR to meet the capabilities of future displays as well, the developers explained. When properly implemented, HDR content remains backwards-compatible with today’s technology while making available metadata and picture information that will produce brighter, more dynamic, and more colorful images on future TVs. Content can now be smartly scaled to use the color depth and dynamic range of the display, which means the content you watch today will actually look better on future display technologies.

“HDR represents a new way of thinking about video,” Munsil said, “with a completely different approach to transfer functions, or what we used to call ‘gamma,’ and that meant that a bunch of old patterns just plain didn’t work anymore. Video is now encoded for very-high-brightness devices, and then has to be remapped by the display to fit that display’s actual capabilities. Needless to say, every display does it a little differently — now, with the UHD HDR Benchmark enthusiasts and professionals will be able to get insight into exactly what the display does when it makes those important remapping decisions.”

Most of the patterns provided on UHD HDR Benchmark are encoded in multiple versions, with metadata and peak levels adjusted for a wide variety of HDR display technologies, according to the developers. And like the previous S&M discs, the new disc uses patterns created from scratch using in-house software.

“There really isn’t any other way to make patterns that we can stand behind,” said co-creator Don Munsil. “We build every pattern using our own tools, written from scratch in C++. If a pattern needs to be generated directly in a very specific color space and data format, we generate it in that color space and format; we’re not limited to what you can do with off-the-shelf graphics software. In a few cases we’ve had to create our own format, because no existing file format could represent the pattern we needed to create.”

UHD HDR Benchmark includes new editions of some favorite patterns from earlier discs, plus many new patterns exclusive to Spears & Munsil.

“We’ve created the very best single pattern for evaluating which color space to output from your UHD player or set-top box,” Spears explained. “The problems of artifacts caused by color conversion and video processing remain as relevant as ever for HDR and UHD, but HDR adds exciting new problems to all the old ones. We rebuilt the color-space evaluation pattern from scratch, and put in one place everything an end-user or professional evaluator needs. Every pattern we make goes through that same process, and is refined again and again to make it clearer, simpler, and more precise.”

The disc also includes a complete suite of test patterns designed for use with spectroradiometers and colorimeters. “These patterns are tested by real industry professionals, multiple times over multiple iterations, before we put them on the disc,” Spears said, noting that “they are the same patterns used regularly by the same people who produce your displays, players, and movie content.”
