Nah, those phosphor strips of that screenshot on the left are plenty coarse to be achievable with a consumer grade CRT. Throw in the fact that European sets pretty much all had RGB and it’s pretty realistic. Although most of us only heard about RGB cables with the advent of chipped PS1s and pirated NTSC discs (they oftentimes only displayed in black and white and RGB cables were the widely known fix for that).
EDIT oh by the way, the community CRTgaming also made it over here to Lemmy :-) I’ll have to post some content there…
