It's a damn big subject. The only feature it seems to have better is adapting rendering pixel density per screen, and I seem to recall there was ways to set higher resolutions and downscale them independently.

I am sad and irritated that in 25 years there is some things that have distinctly gone backwards. The LCD technology, and the colour/contrast/saturation thing is a definite step backwards. Part of the reason being that saturation is a more complicated type of filter than gamma curves and brightness height, it works by applying a gamma across the axis of the three colour layers, increasing the stronger one and decreasing the others, eg, if a colour is reddish, saturation increase means raising the red brightness AND decreasing the blue and green.
Every time I see the color calibration settings on computers I just wonder how it is that the manual says "calibrated" and in actual fact, totally not. And for some reason, you have to buy a piece of hardware to make the colour profiles modify this saturation thing on linux. Nvidia driver has it, but AMD doesn't. Still. But it does on windows. AMD you can affect vibrance on X, but not on Wayland.
Fiat clown world technology. Without interoperability, and consistency, their fascism is really obviously cheap and aimed at weak targets.
