What is different in the quality of movies seen in the big screen today?

Take for example the movie, Skyfall. I noticed that on screen, its so called “texture” looks so polished. So glossy. None of the usual bit of a grainy texture I used to detect on screen. Is this because they are using digital cameras and not using 35 mm films anymore?

I think it was George Lucas who started this with the Phantom Menace.
