Description
This adds a CSS property to control the brightness of high dynamic range content.
It is very similar to UIImageView preferredImageDynamicRange API, in that it specifies qualitative HDR levels (standard, constrained-high, and high) that may be interpreted by the user agent to provide the best user experience, instead of quantitative HDR headroom values.
I don't see any abuse considerations. As a web developer it might be quite attractive to just specify
:root { dynamic-range-limit: high }
as why would you not want all your HDR images to look as good as possible.
