On the Apple TV 4K, the YouTube app has always been lagging behind, both in terms of resolution, framerate and even colors.
It seems that since version 2.07.01, the automatic switch to HDR finally works correctly, at least on tvOS 16 (Thanks Théo). Obviously, it is difficult to test with all the televisions on the market, because the management of HDR (like framerate) is sometimes very variable. Do not hesitate to tell us in the comments, while specifying your version of the app, your television and if you are on tvOS 15 or 16.
let’s remember that HDR means
high dynamic range (opposed to SDR), and allows more amplitude between high and low light -basically, some kind of on-screen light will make it look much brighter than on regular TVs and screens. Only downside, to enjoy it, the whole channel must be in HDR – currently, very few TV channels broadcast in HDR for example, while Netflix or YouTube now offer this format when available.
You can test it with our last two VE tests, which are shot in 4K60 HDR10. These formats are quite complicated to edit, transcode and export to YouTube, but if you have suitable equipment (recent iPhone, HDR TV…), this large dynamic range is quite nice to watch:
