but the frame you posted showing the excess film grain looks suspect to me because its so uniform...almost like a brush or effect one would use in Photoshop...
Your thoughts?

Uniform? I suppose you're referring here to the presence of it on the frame, not its actual "look". If that's the case, then yes, it's basically uniform.
Film grain is actually the mass of silver halide crystals suspended in the gelatin layer of the film stock's emulsion, which are light-sensitive and ultimately lead to the capture of the latent image. The size and distribution of these "grains" of silver halide crystals differs with stock, and is largely part of what determines how "grainy" the stock is. But the distribution across the entire emulsion is basically uniform. So while the size and pattern of the grain may change, it's always there across the entire frame.
