I don't know whether humans or aliens work at the CSS standards bodies, but as time progresses from the advent of the internet the end result gets more and more unusable.
This is important for people who care about color. If you're more of a "sRGB ought to be enough for anybody" person, it will always be there for you.
Blessed are the colorblind, for whom 4 bits/channel is plenty, and color accuracy is a punchline. I’m sorry, normal-visioned person, is this display calibrated so poorly that orange and green are the same color? Welcome to my world.
Hello, fellow colorblind person! Certainly, better color expression doesn't hurt us. And depending on the severity of your color deficiency, the wider range of available colors in large-gamut color spaces can enable us to more easily distinguish between colors that might otherwise appear similar or identical in sRGB.
