What is the Spears & Munsil UHD HDR Benchmark and what does it show about HDR10+?

The Spears & Munsil Ultra HD HDR Benchmark (2023 Edition) is a three-disc 4K Blu-ray test set created by video calibration experts Stacey Spears and Don Munsil. The disc encodes the same source footage simultaneously in HDR10+, HDR10, and [multiple HDR formats],  all mastered at 10,000 nits, making it the definitive tool for comparing HDR format rendering on the same display with identical source material.

A key test scene features horses in a snowstorm. On a display with poor tone mapping, snow clips to pure white, losing all texture. On a display with accurate HDR10+ implementation, the scene reveals natural snow texture and horse coat detail,  exactly as the colorist intended.

Because the same scene is encoded in all three formats on one disc, the benchmark allows direct, side-by-side format comparison under controlled conditions.
