Computer displays are in the 256 8bit colour space. My tv is a Oled 55 E6 that I use to test my HDR works. IN SIMULATION OF LIGHTING(Like videogames) it is no longer a creative choice but a system that simulates how colours are suppose to be graded from 0-1000(HDR10). In this game when you turn of HDR you can see the intended colours by the developer.
Here you go I also grade movies in HDR.

Please don't say an art major doesn't understand how colour is suppose to look.You don't ask colour blind people to colour correct your video files do you? My degree is about Art and implementation of things like colour theory.
Again I waiting for someone to try and discuss HDR but nobody here seems to know WTF it is suppose to do. A true HDR implementation like in Uncharted 4 or Horizon or Destiny2 does not lose colours or black levels but increases them and their quality.
