No wonder I felt a twinge of familiarity when I saw the EE BD transfer at the 10th anniversary theatrical event. I’ve always wondered if it was closer, especially when I went back to those bootleg DVD screens where Rivendell didn’t look like the official DVDs - did you look at the link I posted earlier?

I would be careful about the Two Towers teaser as a reference though, that was attached to prints of FOTR in spring 2002, 8-9 months before theatrical release. So the grading might have not been absolutely finalized yet. I do agree with you that the home transfers may be wrong, let me dig up the Asian bootleg screenshots of TTT that were also an Internet meme in the early 00s, they were also presumably from a screener or something prior to the official DVDs.
