Gregory's Server@leaverou Question as a user: I have Lightroom Classic set to export as Display P3 on the (untested!) assumption that raw could exceed sRGB. Most content in my photos is within the sRGB gamut. With clipping, it seems to me that viewing my photos on an sRGB display is almost always fine (except some 8-bits per channel precision is wasted).
With gamut mapping, wouldn’t all my photos get their gamut squished on an sRGB display just because they declare Display P3 (without fully using it)?
@hsivonen gamut mapping algorithms used for photos are totally different and focus on maintaining the relationships between the colors in the image, whereas in the CSS one we focus on preserving as much of the individual color “identity” as possible (hue and lightness). CSS gamut mapping does not affect embedded images.
