Well....not all BD are DNRed...have watched recently "Venus Wars" (1986) it keeps all the original grain if you like that I recommend you.

Does it look like it does on LD (natural) or does the grain look artificial and overcompensated for? Blu Ray has a tendency to bring out defects much more than they were originally seen even without remastering.

This happened on a number of Japanese anime film re releases. One I have is the Macross DYRL? DVD remaster boxset and the grain looks terrible and over done, much prefer my super natural Perfect Edition LD box. The first LD I ever owned too.

No, not really. While grain is technically possible on Laserdisc, it's never really what you see in major features. For films shot on 8mm (and, in best case, 16mm) Laserdisc could have some of the grain remaining although the noise of the medium itself will most likely be overwhelming. For 35mm, the grain is simply too small in order to be intact on Laserdisc.

With high enough resolution and decent compression algorithms, both H.264 and H.265 are capable of represent the grain of pretty much any film regardless of stock. And this can then be used for home video distribution.

I recommend having a look at Arrow's Blu-Rays for anyone who doubts my statement. They put more effort into their masters than Criterion and it looks fantastic. Easily among the most film-like experiences you can have in your own home.
