Anyway, would you say the projection was accurate to the old German DVD, the one that was transferred from a print?
No. The colours in that version are washed out, and it was not transferred digitally it was very obviously done by telecine which never produces a projection-accurate result regardless of whether you’re using a release print, a TV print, or whatever. I do not think it was even transferred for DVD - it looks like they used a broadcast tape literally transferred in the 1980’s for that release. It’s a full-screen transfer, outside of the US no one did full-screen transfers for DVD, even in 1997. And when they did the first digital restoration, and broadcast it, it was in widescreen.
