I can confirm this. Would be a nightmarish process to fix. Even After effects artists would struggle fixing this. Because this is clearly not one for those “FIX IT IN POST” items. Disney put that burn in for a reason. (FAN EDITS) :{
My guess the studio might release and extended edition of directors cut in the future. To maximize there profits.
And not only that we do not even know of the level of production quality of these scenes, from an audio perspective.
