. A very slight amount of CA seems to help realism, such that I expect it has an effect in cinematography. It's certainly present in every camera lens to some degree even if not to the extent of clearly separate colour fields.
Yeah, the guys here came up with a few other tricks, like grime on the camera lens that gets more visible when there's a light in front of it and so on. There may be a new trailer coming out soon where I might be able to point it out...
