I just don't get the complaints about "use proper art" when it comes to games. Most of the time the game has some other, far more glaring, visual issues (anti-aliasing, clipping, icons-not-matching-items).
I have a suspicion that when you're looking at (and generating, because you then look at the results) AI generated images and text more you get desensitized and are more likely to say that something looks okay when to other people it won't.
How come pretty much every modern UI is garbage? Are the devs just lazy? Like google.com on mobile does not have parity with the desktop version (there's no "set specific date range option).
In anything you do, there's a point where you've got to say "okay, this is good enough" and ship it. In fact, I would argue that using pixel art itself is "settling" in the majority of cases.
