> 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?

They are distinct but interconnected concepts. Color gamut describes a color spectrum while SDR/HDR is about luminance range.

In practice, different gamuts do correlate with sdr / hdr, but there are edge cases (like Apple's 2017 P3 displays, which are not HDR) and I think its not clean enough to live without a separate dynamic range signal.
