What are these highly popular TV models with these blue skys? When was the CXA2025AS first integrated into TVs? Why is this decoder so special, as opposed to other ICs? Is it because the matrix is different? Every decoder will have a different matrix. It's why NTSC stands for 'Never the Same Color' but you are supposed to use the tint and phase control to get the correct colors (that's why they are there), and I've never seen a TV that couldn't be corrected. The only objective criterion I have seen for how an NTSC television is supposed to look is the NTSC standard itself. To support this standard I can name dozens of consumer-grade television sets that can be tuned (by the consumer) to look pretty damn close to the standard.
MAME already let's you adjust the colors, so if you want shitty colors you can do that now, and keep the save file for personal use, or put it up on your GitHub if you want to help others achieve shitty colors, too, but I don't think it should be an official option since it doesn't seem to be founded on any reality, but is rather a 'this looks kind of like how I remember it so it must be correct' conjecture.
The alternative is to emulate every NTSC IC in MAME, along with the options to control the service parameters like a real TV. This would probably be better served as a separate television emulator.
