I need movies from the 20TH CENTURY on UHD, too!

I disagree sir. The finer resolution of 4K means that grain itself is rendered finer, now I DON'T mean that it suddenly disappears from view but it DOES come across less coarse than what it would do on an equivalent BD presentation. What we see on Blu-ray specifically is as good as compressed 1080p will allow, but it's still not as finely grained as what the source holds and 4K's spatial resolution will get UHD closer to that.

As for grain reduction, I didn't say anything about "using it on Ultra HD" just because, I said that it's part of the package with HDR because of how the higher range exacerbates noise/grain. I'm sure Penton will be along to elucidate in due course.
