There are plenty of good scientists and engineers who do psychedelics. If what you say were true, I think at least one of them would have figured out what the sense data is caused by in the environment and have set up a demo such that they can reliably react to a signal sent by a skeptical tester who turns the demo device's power switch off and on, in order to provide evidence to skeptics of their superior perception ability.

Related and interesting, there are some common visual patterns across many hallucinogenic experiences, “form constants”. Possibly related somehow to the organization of our visual system.

It blew my mind when I learned these exist, and especially when I learned there has been apparently little research into them. Maybe more informed minds than I have determined there’s nothing to learn from them, but it seems like there would be insights to gain about how we see.
