This is a pretty cool discussion and I know where you are coming from mate.

I agree that a 2K scan of the 35 mm o-neg would not be as good as a 4k scan of the same 35mm o-neg.

But every official study i have seen claims that the all important release prints are less than 1 k:

I think this explains why Lucas went for 1080p for the prequels.

A digital release at 1080p is better than a 4th gen 35mm release print(which is what the original trilogy was).
