> But when using something like rec2020 which has a wider blue range, the mapping gets dull blues. I'm finding the same thing, and I think it is a consequence of better hue preservation in OKLCH. Mapping in CIE LH gives you a higher chroma, but preserves hue less well. These examples below require an implementation that supports `color(display-p3)` so try a recent Safari TP. Otherwise you won't see the actual colors, just black. They show Rec2020 colors being brought into the `display-p3` gamut by Chroma reduction (constant hue, constant Lightness) both with and without a final clipping stage. The upper part of each diagram shows the resulting color (if inside `display-p3`; red if not) and the lower part shows the _linear-light_ `display-p3` color components.
