If you wanna listen to it in Dolby Atmos, I hear that’s pretty good and it’s probably cleaned up
If you wanna listen to it as it was, I would imagine there’s a lot of crackles and Vinyl sounding pops.
The Atmos track on Dr. No is heavily noise-reduced and rolled-off. I don't care for it. The movie also has absolutely zero need to be in Atmos. I might understand the argument to expand the score to stereo, but anything beyond that is pointless.
The mono has some hiss (no crackles or pops), but is a lot livelier than the Atmos track.
