I think the top right corner blob is just a signal to the projectionist to
start the next reel. It is something like 10 seconds before the next reel
starts. If you watch the movie, there's typically a scene change 10
seconds (or whatever it is) after the blob. Theatres now splice all the
reels together for playback, so the blob is pretty meaningless (unless
some still play the show reel by reel).
