The problem is that people have a limited amount of caring and markets are really good at taking advantage of consumer ignorance. If you care about color rendering but don't know what color rendering is, you can't shop for it (and if you do know what it is you can't shop for it if it's not on the spec sheet).

This drives me absolutely insane. When we were shopping for a TV for the living room a few years ago I wanted a 120Hz display. Finding one was a pain in the ass because all anybody wanted to list in marketing material was the backlight strobe rate; you had to dig and dig to find the panel rate.
No, I don't care that you can flash the backlight at a thousand Hz, I want an actual panel that's well synchronized with 24FPS content, and I don't want to spend hours of research to figure out which displays have one.
Yeah, I'm back to wanting a curated shopping experience. I don't want the cheapest thing. I don't want multiple options- thats worse than nothing. I don't want to worry about counterfeits or knockoffs. I don't want to do research, consult the relevant /r and then look through comment history to see who is paid to say what. I want a store to have an opinion and stock high quality stuff. I would happily pay a premium to offload decision making.
Instead of force, maybe voluntary? Publish/promote a set of standard measurements for consumers, then let consumers drive the manufacturers. "The Market" will follow the consumer if the consumer is strongly inclined about its desires - I think we have seen this play out in other consumer electronics niches...
When I was a teen, I wanted an alligator on my shirt, and not too long after I started seeing simulacra shirts... Enough of a demand for more than one entity to mimic it...
