Proper HDR support would be great!

I recently bought a QD-OLED display as their prices have fallen hard, so HDR support is something that has become quite preferable to have nowdays (for both games AND applications, like Lossless Scaling - HDR support there is invaluable when you're gaming in HDR). I'm sure plenty of other people would benefit as well 👍
