> what if we do an enum called dynamic-range, with values { standard, high }.
The currently defined CSS [`color-gamut` media feature](https://drafts.csswg.org/mediaqueries-4/#color-gamut) 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](https://drafts.csswg.org/cssom-view/#the-screen-interface)? (The [`color` media feature](https://drafts.csswg.org/mediaqueries-4/#color) 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 `screen.video` sub-object.
