Samsung QN90B and Apple TV 4K 2022... where's the HDR10 plus???

Format indicator icons in the Prime Video app come from the app itself, as programmed by Amazon for each platform. You’ll have to ask Amazon about their indicators and possible differences between platforms.

Try bringing up your TV’s info screen on the current stream, if the TV has support for such a function. That should tell you if you get HDR10+ at that moment, regardless of icons by content providers.

If you can browse Paramount+ channel in the Apple TV app, look for e.g. Significant Other, then look for its format details. It should mention HDR10+ there.

Greetings Russell Wolff,

This article provides great information and steps you can use to get HDR10+ working on your Apple TV 4k: About 4K, HDR, HDR10+, and Dolby Vision on your Apple TV 4K - Apple Support

Please let us know the results when you're able.

All the best.

If you connect the Apple TV 4K box to a Samsung TV, then you shouldn’t be able to get Dolby Vision in Settings. If you see that, then try resetting the video settings, to have Apple TV re-establish what the screen is capable of.

You may see content indicators for various formats; that is different. I don’t think you will see HDR10+ labeled content in Apple apps (some content could be DV & HDR10+ both though), but you should see it for select content in other content provider apps, like Amazon Prime Video, Hulu, Paramount+, YouTube, and a few others [1]. Amazon seem to be going all-in, with all HDR titles now also in HDR10+. Not sure how they managed that at once for a complete catalog, unless through upconversion of sorts.

Hello Russell Wolff,

While we can't provide a reasoning to what you're seeing, if it's something you'd like to report directly to the team that handles it, you can do so here: Product Feedback - Apple

If you're still having an issue playing the actual HDR10+ content, then reach out to Apple directly as they'd be more equipped to look into the issue further with you: Get Support
