> The chaotic nature of film grain [...] produces noise that originates from the natural world, and makes each frame unique. Noise generated through interaction with a fixed-pattern sensor and locked to a manufactured grid is fundamentally different – closer to mathematical white noise.

There's a possible parallel here in audio: Pink Noise [0] has a profile is closer to natural sounds in the physical world, such as falling water. It might be better/more-satisfying to humans because it's closer to what our brains have learned is "correct" noise.

I wouldn't be surprised if there's a similar phenomenon in the visual realm.
