There is plenty of evidence that these changes happened during release and the DVD/BR is 100% faithful to one of the releases. I found multiple audio streams in the camera prints and all these changes can be found at that point.
Just to be clear, you’re saying that the issue is variability in the theatrical run?
Yes. I have more than one camera print and one has changes from what came out on home video and one did not. It may be domestic vs international English. I have no clue where the English language track for the camera prints came from. But I do have two completely different ones. Particularly that line by the women in black and white as she tells the large alien something. One has her line, one does not.
