At least I can’t see much grain in the 2002-DVD (don’t know if it’s SD-compression or grain - maybe my eyes are just used to HD so much that I can’t see grain in SD-material anymore 😄), but there’s definitely a light “flicker” which gives the picture this filmic look. If it is grain then it’s of very fine structure.
The Laserdiscs from the 90s have also been in 2.35:1, maybe the restauration used on the 2002-DVD was made already back then?!
