All the examples look to me like they might have been made to intentionally look like theatrical back drops.
Granted I don’t watch a lot of movies, but the production quality of TV I watch has improved by leaps and bounds over the last couple decades and continues to do. I don’t know if that automatically extrapolates to movies but I’d be shocked if they’ve had such sharply different trajectories. If anything, I was expecting this to be some kind of an uncanny valley sort of complaint… not a pretty obvious creative choice.
It seems like what keeps getting worse as the technology improves is the pervasive, uncharitable hot takes.
