Don't CRTs also have a degree of motion blur, even close to undetectable, due to the persistent nature of phosphors?
I think your right, on some old 'star field' style effects in some demos, you can see slight 'warp speed' trails, due to phosphor persistance.
On the other hand, lots of 2d games from old systems use phosphor glow to blend colours, deliberately so. These can look damn ugly on LCD, Armalyte (c64) is a good good one to look at.
There is hope though, I read that someone is working on a 'phosphor glow' filter for emulators. Won't help those of us with real hardware though
