That's a tough one. Only because you would have to go into extreme detail, to explain all those. If you're looking for the best possible release on a certain movie, I would read the site reviews, or reviews from members.

Or, are you trying to make sure your TV is properly calibrated?

I am not the most trained at this, but for movies that were originally shot on film, a great way to see if there is DNR or not is to look for film grain, which will appear as a bunch of dots/"texture" on the film that personally reminds me of the texture of sandpaper. This makes the film not have a smooth look to the colors on it. This, in turn, makes it look different from "clean" digital camera shots and DNRed films and if present normally means that there is little or no DNR on the film.
