HDR10+
An open, royalty-free HDR format developed by Samsung and Amazon that adds dynamic metadata to HDR10. Functionally similar to Dolby Vision but without licensing fees.
HDR10+ extends HDR10 with scene-by-scene dynamic metadata, letting displays tone-map dark and bright scenes independently. Unlike Dolby Vision, HDR10+ is royalty-free.
Where you'll find it
Samsung TVs (which don't support Dolby Vision) lean heavily on HDR10+. Amazon Prime Video is the largest catalog of HDR10+ titles; Apple TV+ and Disney+ favor Dolby Vision.
HDR10+ Adaptive
Adjusts the tone curve based on ambient light, similar in concept to Dolby Vision IQ.
Practical advice
If your TV supports both Dolby Vision and HDR10+, you'll rarely pick manually — players negotiate the best available format. If your TV supports only one, your streaming experience is gated by which services use it.
How to use HDR10+ in a real comparison
An open, royalty-free HDR format developed by Samsung and Amazon that adds dynamic metadata to HDR10. Functionally similar to Dolby Vision but without licensing fees. In practice, this is most useful as one part of a decision rather than a standalone quality badge. Compare it alongside the workload, room, ecosystem, budget, and ownership constraints that apply to you; the strongest published figure is not automatically the best outcome for every buyer.

Avoid the one-number trap
Manufacturers can describe the same capability under different conditions. Compare like-for-like variants, check the unit and test condition where available, and use a head-to-head page to see whether a measurable difference is material for your own use.
vsMars presents structured catalog values to make trade-offs legible. The linked product and spec pages are the right place to inspect the underlying values before buying.
