Actually, the color space function is super and important. But this was unfortunately implemented very half-heartedly.
For example, current iPhones have the P3 color space. DCI-P3 for examples has by far a much bigger color space than sRGB. My display with which I make my screen designs supports also P3.
There are certainly many who also make screen designs for televisions, etc. There are e.g. REC 2020 or Rec 709.
So it would be great if it is possible to use the system internal color systems.
