> This is similar to good audio engineers back in the day wiring up a dirt cheap car speaker to mix albums.

Isn't that the opposite of what's happening?

I have decent audio equipment at home. I'd rather listen to releases that were mixed and mastered with professional grade gear.

Similarly, I'd like to get the most out of my high-end Apple display.

Optimizing your product for the lowest common denominator in music/image quality sounds like a terrible idea. The people with crappy gear probably don't care that much either way.
