Displays with a wider color gamut than sRGB -- the average of a sample of early-to-mid 90s CRT displays -- have existed for decades now. Not to mention, Mac OS X supported color management (and exporting color profiles) since its first public release in 2001. Even today, it's trivial on a Mac to e.g. connect a monitor and export its color profile into an ICC file, which can then embed into a QuickTime container, PNG image, etc.

I don't think I've seen more than 8-bit monitors before mid-2010-s, except for some DICOM-specialized grayscale monitors. > Even today, it's trivial on a Mac to e.g. connect a monitor and export its color profile into an ICC file And you can use the ICC profiles in Wayland: https://wiki.archlinux.org/title/ICC_profiles#Wayland https://wiki.archlinux.org/title/ICC_profiles#Wayland This capability has existed for a long time. The protocols being merged allow _each_ _application_ to work within its own color profile, including more-than-8-bit colors, exposing this information to the composer. The composer can then dynamically translate the color formats, according to the output capabilities. So if you move a window from an HDR-capable external screen to a laptop's crappy LCD, you'll get reasonable image, instead of a black window (or a washed out image).

  color space and bit depth aren't the same. you can have 8 bit P3 vs 8 bit SRGB (etc). A colorspace is a combination of a whitepoint, a gamma transform, your color primaries, and a bit depth.

    What is a good, concise resource for all this stuff for the interested layman? I am not familiar with anything but the very basic "RGB" and know basically nothing about how video screens really work.

      Basically: The colors on the screen will look more like on a photo print. In addition, if your monitor supports more than 8 bits per pixel color information, then you'll be able to see more vibrant colors.
