Guess it depends. I haven't had a CRT TV for many years, but I have an old multisync CRT monitor and I can clearly see the individual raster lines (close up of 320x200 progressive scan: https://i.imgur.com/Osc4ZMm.jpeg). At normal viewing distances it's not noticeable though.

It would make sense to adjust the "line width" (focus!) of the scanlines so they blur into each other. But on a multisync monitor, this would be matched to the highest resolution it can display. Without fancy defocusing circuitry, of course if you display only 200 scanlines on a monitor capable of 5x as many, you're going to get a lot of black space between them. This bothered me personally, in those days, in my case with a 20" CRT monitor and emulation of my old C64 environment. Modern "CRT emulation" is better than the real thing, in this case.

Yes thats what it was all about. The pixelated game graphics were made with that and other CRT properties in mind.

Yeah, and I seem to recall reading an article about some of the good old tricks (think it was about the Aladdin game?), but unfortunately I can't seem to find it now. Doing the dithering (by hand) just right would give a good effect in practice. Things made for real higher resolution monitors looked bad on lowres CRTs though (with very distinct scanline effects) as I recall like the menubar in my screen cap, even at a distance.
Deluxe Paint, ah! fond memories!

21" by chance ? Why would someone use 320x200 on a monitor when only the very old DOS games need such a mode ?

14" 1994 vintage Microvitec. Very popular monitor for Amiga systems because it supports 15KHz horizontal refresh rate modes (PAL/NTSC TV standard - for games/demos) up to 31KHz+ (VGA) for nice flicker free 640x480 60Hz display ("productivity") modes for serious stuff.
