But… of course there is? A record of a real thing is different from a statistical simulation of it.
But also a simulation called compression of a real thing is different from that real thing, so that purity test had already been failed
[EDIT] My point is "film grain's not more-real than algo noise" is simply not true, at all. An attempt to represent something with fidelity is not the same thing as giving up and faking it entirely based on a guess with zero connection to the real thing—its being a representation and not the actual-real-thing doesn't render it equally as "impure" as a noise-adding filter.
It may as well be stimulated because you won't see the difference! So now you've imagined some purity test which was never true, so you have nothing and start hallucinating some hyperbolic AI thing
