Great work on this. It does look very similar to me, too. I'm not sure if that's because these effects are designed to emulate real noise, or because this noise was generated by those effects, but it does provide an avenue for this to be faked and that's helpful to know.
This got me thinking about the camera shake. I thought there might be a tell in the camera motion, for example if this was implemented in a naive way then I would expect both axes of the camera shake to have a similar standard deviation.
I used phase_cross_correlation to check adjacent frames. This technique isn't perfect, especially in the presence of noise, but it picks up well on full-frame motion. You can see when the plane is not in the shot it doesn't have anything to measure (motion goes to zero). Even at the beginning I would expect a little more shaking to be measured.

What I see is that the y shaking is consistent and large, but the x shaking is relatively smaller in the middle section (around 800 frames), and maybe similar around the 600 and 1200 frames section. The x shaking has more low frequency power because the video is panning left and right, which is to be expected.
I think this could be replicated by simply setting some scale on the camera shake automation. Does anyone know if there are any standard camera shake automation controls that, by default, provide more y shake than x shake? I can try to get more precise numbers on the standard deviation in these different sections. Hopefully it's the same, and I'm just being tricked by the graph, because if the animator also automated the camera shake scale that's another surprise to add to the pile.
