Samsung, Amazon Unveil Yet Another HDR Standard
And here I was thinking the whole point of having standards was to homogenize offerings for a given feature, ensuring the same minimal requirements were met by anyone (or any product) looking to carry a sticker emblazoning its capabilities. Yet here it is, another HDR standard, which Samsung and Amazon are calling HDR10+.
The HDR10+ standard looks to slightly bridge the gap between the HDR10 standard as certified by the UHD Alliance, and the Dolby Vision one, which boasted better HDR reproduction whilst carrying higher specifications to be adhered to. The greatest change in HDR10+: the adoption of Dynamic Tone Mapping, which stand upon variable dynamic metadata to help adjust brightness and contrast in real time, optimized on a frame-by-frame basis, a feature present in Dolby Vision but lacking on the UHD Alliance's HDR10, which resulted in some overly darkened bright scenes.
