A well worn theatrical print won’t be anywhere near a pristine 4K scan of the negative. It will be like seeing it back in 1980 after it’s been playing for a month pr two. Kind of grindhouse. And the original mono track. But you will see little things even full frame video transfers have masked out all these years. And the Steadicam shots take on an IMAX feel.
I don’t know how this will be made available yet.
