Video is also higher resolution, as the pixels flip for the high resolution world by moving through it. Swivelling your head without glasses, even the blurry world contains more information in the curve of pixelchange.

Correct, for the sprites. However, the walls in Doom are texture mapped, and so have the same issue as videos. Interesting, though, because I assume the antialiasing is something approximate, given the extreme demands on CPUs of the era.
