Yeah, I don't recall shimmering ever being noticeable during the PSX era, but when I see videos clips of actual PSX hardware, it stands out to the point of being highly distracting.
The shimmer and dithering are not really noticeable on CRTs. Maaaybe if you had a really fancy Trinitron or another of the last-generation ultrasharp flat screen CRT TVs, it would be noticeable, but those weren't mainstream until pretty comfortably into the PS2+ era.
Granted, I was a kid then. If you were a professional artist or something in the 90s, I'm sure you noticed.
