Re: [csswg-drafts] [css-color-hdr] Add mechanism to query HDR headroom (#9306)

If it's the case that `referenceWhiteLuminance` depends on viewing conditions which influence screen brightness, then WebKit objects to adding that. A web page should not be able to detect the viewing conditions in effect; it should not be able to detect when you walk outside, for instance. And I don't think there's a user prompt that could be worded in a way that users would understand that this access could be gated on.

The preferred approach is to allow authors to supply a list of assets, and have the UA pick the appropriate asset (like `srcset`).
