In ESB when Han says “Then I’ll see you in hell.” that line used to be “Then I’ll see you in HELLLLL!!!” with the “hell” part really screamed and loud, later on they seemed to mute that down a lot.
Is this true, a fact?
Well at the least it is true that I heard it in theater way back with the “hell” sounding a lot louder. I suppose there is always some chance it could just be that some theaters had speakers that had some sort of spikes that matched his voice and the way he said that and it made it sound more boosted, although that seems far less likely and reasonable of an explanation than that they just dampened it down a bit to not stress a semi-swear word as much or something.
This seems a little anecdotal to be included as a change here? Maybe it is more likely to be an issue with the theater you were viewing the film at, with nobody else apparently having this experience?
My little town cinema struggled with some TLJ scenes - there was pixelation during key scenes with explosions. At the larger cinemas there were no such pixelation problems.
