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.
The German DVD transfer (the old MAWA one) was indeed from the 1980s, and was actually done for the VHS and a later LD release. It’s just been reused for DVD.
