I did see it very slightly on the clouds in the Fox Intro, and did not see anything on the wall behind Han when talking to Greedo, but I went through SW again and still do not see this at all, like I said, hopefully the other guys will chime in as well, I was going to look at the originals but no need to look at them if I do not see it on mine.

*edit - I just went through Jedi and did not see any of what you mention there either, so to me at least, this is the best 97 SE preservation, you must have bionic eyes, because I see none of it at all on all 3.
