Is it possible to only sample up to the frequency of the human eye? And the prove it for that as an upper bound?

These seems like an almost philosophical question: can you certify physics?
Also at small enough pinholes it seems quantum weirdness will emerge.

The only way I see that this is possible is if we have a real life counterpart for our synthetic scene, and basically look at how different the rendering is when compared to what a human sees. The physics that is used in current graphics renderers will mostly be a approximation of the real-world, so it can't really be "verified" in the absolute sense.

Verification seems like it would be limited by the effects that tracing rays can produce as well. This will never be able to reconstruct wave-based illumination effects, such as diffraction and speckle.
