It certainly won’t have more detail than the original negs, I don’t see how that could be possible as the prints are derived from them.
If they had more detail then I think we would be breaking some fundamental laws of physics 😃
Depends, it’s well known that the original negs are really beaten up. The prints are derived from it, sure, but they were derived from a nearly 40-year younger, pristine negative. At least, that’s how I imagine those claims make sense. I recall Mike saying something along those lines before.
