Re: [csswg-drafts] [cssom-1][mediaqueries-5][css-color] Dealing with bi-plane (video/graphics) when reporting values (#4471)

> what if we do an enum called dynamic-range, with values { standard, high }.

The currently defined CSS [`color-gamut` media feature]( uses keywords to describe existing commercial standards: srgb, p3, rec-2020. Does that cover what you need, or is that a distinct concept?

Or, could it cover what you need when combined with a measure of color bits per pixel, as suggested by the example in the CSSOM View spec describing [the `colorDepth` value of  the `Screen` interface](  (The [`color` media feature]( provides similar information to `colorDepth`, although not in a directly interchangeable format.)

It would definitely be preferable to harmonize the concepts used in media queries with those used in CSSOM View, even separate from the bi-plane considerations.  If we can do that, then it seems like a natural extension to handle bi-plane rendering by extending the necessary media queries to have video-* versions, and extending the Screen interface to have a `` sub-object.
