Cut your nose to spite your face then. You’ll keep paying for genocide even if you won’t “vote for it.”
The things you can do are support groups and politicians that will push the country in the direction you want it to move.

One of the concerns I would have with custom ROMs for TVs is that I think a lot of the image processing magic that makes the image look good on these high end displays is done in some proprietary method that the custom ROM wouldn’t be able to use. Either in software or in hardware.
The magic of the high end TVs isn’t actually in the panel itself as much as in the driving of the panel.
