I work in the film industry and can say, with certainty, that TNG was not shot with the same consideration.
Television back then knew it was being mastered for SDTV and the artists had a good idea of what it meant they could get away with compared to something that would be screened in 35mm. Final screening medium has always been the most important consideration, not capture medium.
Audiences have also gotten less forgiving of visual quality and less willing to suspend disbelief as the bar for quality has steadily risen. It means that shows are both working on higher definition target mediums and under more scrutiny than ever.
Like, I love TNG but go watch and tell me that it looks half as good as SNW.
I don't know. This would dovetail well with a bunch of studies that have found verbal and physical abuse of retail workers at an all time high since the pandemic. Similar studies have found the same thing for road rage.
There has always been some fraction of poorly behaved people, but that fraction seems to have become larger since the pandemic, whatever the actual mechanism that caused it is.
