A couple of years ago, I was lucky to see Lowrence of Arabia in a local cinema with a 70 mm film projector. The film was originally shot on 65mm and it looked fabulous on the big screen! I don’t remember the film grain being an issue. I usually notice it at the start of the film but then quickly get used to it. It’s also likely that the picture quality was cleaned to some degree.

I presume your Blu-Ray transfer was processed conservatively. Digital filters to remove film grain can introduce their own artifacts which degrade the image quality and make the picture look different from how it was originally intended to be seen.
