Yes but why add the confusion of gamma correction etc and a small gamut?

Probably an artifact of the color space used.

Are you speaking of https://en.wikipedia.org/wiki/Gamma_correction ?

The color you will use isn't in SRGB, but is in other color spaces such as Rec2020.

Doesn't this get in the way if you're doing graphical work where you need to know the colours are right?

That's more a problem of the camera and ISP and not color management and display.

The colors don't look like they used to because modern displays are much brighter and higher contrast. (and are 2.2 gamma not 1.8)

Not really, it's the same color primaries just without the non-linear transfer function.

It's a wider color space. It improves the color range of everything, assuming the source hasn't been flattened to SRGB.

Tell me more about inferiority of pure RGB goodness :)
