Yes, as you can see UHE has more details, but also a lot of DNR... obviously, it will be impossible to recover the lost grain, but adding a grain plate taken from actual film improves the perceived details and hyde some (but not all) problems caused by DNR... but, as this was the worst offender frame, I think the rest of the movie should be improved a little more than this, and, even it will be not perfect, it *could* be a little bit better than the old MPEG2...
This is the reason why I'd like to receive two clips from both versions; to test grain plate on UHE, and to see if final result could be better than the MPEG2.
