From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Makes sense, I just dont quite get what the compositor does in the case of two videos being played simulatanously both with vastly different profiles (e.g. one mostly red, one mostly blue).
Does the compositor then do correction on a per-window basis, or it just averages across the whole screen. This question is likely outside of the scope of the PR
With color spaces we're talking about standards like sRGB, Rec.2020 and many more. Wikipedia Article
If a video comes with information on the color space it uses, the video player and compositor can now do a more source accurate mapping to your screen than before.
If you also have an ICC profile for your monitor, you'll get the most out of your panel now. Without that, the compositor will assume an sRGB calibration (when not using HDR) and do its best to map a higher definition video to that.
