Re: [csswg-drafts] Define rec2020 color space to use 2.4 gamma (#12574)

> [@simontWork](https://github.com/simontWork) should I interpret your response to mean that you are in favor of the proposed redefinition of the CSS `rec2020` color space?

It needs to be used in conjunction with BT.1886 to be a complete definition.

I think gamma 2.4 works as designed for a dim screen in a dim surround - I don't think that it follows that the same value is correct for all viewing scenarios.  Certainly in HDR, both HLG and the Dolby IQ system show a need for changes for different viewing environments (screen luminance and surround).
