Talking about scan lines, check this out:

It's taken from DJ's GOUT upscale. I sharpened it and tweaked the contrast a bit to make it more apparent, but the vertical scan lines are apparently there in the original, only they get lost because of low resolution.

Yes, the vertical pattern was always there in the original, I've seen it in other transfers as well, it's weird that they got rid of just the horizontal lines for the recomposites, everything including the rolling bars are still left intact. Maybe they were a separate element.
