I have heard German toilet paper is A6, but I never got to verify that. If true, it's one of the more German things ever.

Almost. In Germany, standard tp is 100 × 140 mm, a bit smaller than DIN A6 (105 × 148).

I don't think it is, the aspect ratio seems off, but maybe I'm misremembering (not in Germany right now)
