I agree that the theaters are better than they used to be, but theatrically released movies are mostly four-quadrant dog shit. If you like Disneyesque superhero and fantasy/sci-fi films produced to appeal to as wide a group of people as possible (and by necessity removing any semblance of artistry), that's your prerogative. But don't try to convince anyone with functional eyes, ears, and souls that these films are of higher quality than what used to be released theatrically. There are still quality films being made, and some of them have limited and/or short runs in theaters, but by and large, the offerings at movie theaters are just the same movie over and over, dressed up with different actors and tag lines. Studios gave up on mid-budget films a long time ago, and this is the sweet spot where you typically find quality cinema. Big-budget noise makes them a ton of money, and it's just about all they produce anymore.
This doesn't undercut your thesis regarding enshittening, however. Theatrically released films are just also part of it. Under your rubric, you can probably replace "business customers" with "Chinese market" and you get the same result
