I'm sure some form of training is possible where you get a better understanding of a 4D universe with some limited inference abilities, but with a bad analogy, this would all be "software emulated" with no hardware acceleration - we only have the latter for 3D and we can't update it without a hardware change.

With future improvements in brain-computer interfaces it might well be possible to send a 4D visual signal into the brain.
