@TServo2049: Exactly, they come from an old 2K master.

@zee944: Oh, sorry. I first thought you were sarcastic or arrogant like many people on the internet. I clearly misunderstood and I really do apologies if my tone was a bit harsh.

Anyway, I don't really know if Universal did a new transfer, I just strongly guess because DNR and EE were their cheap option to make the trilogy "nice and shiny" so I don't see the point of rescanning any print at the same resolution to get the exact same render with the same dusts since it costs them a lot of money to do it.
