I will argue or grant that most visual artists do learn to see - even though they very much do not all see the same thing because seeing is also subject to preferences and intellectual choices. Visual arts have certainly gone far and wide. For much of it, even calling it "visual" is a stretch. Sure.
So, bad example.
A better example would be the intonarumori by Luigi Russolo:

But the truth is that this kind of wild experimentation with the limits of musicality has never caught up in the same way as modern art has. There is possibly a reason for that. I suspect that it's far easier to ignore something Duchamp's fountain than Russolo's instruments... just because the latter make noise and you can't stop hearing it unless you run away.
Btw, I heard some recordings of the intonarumori at a modern art museum in Switzerland, and I thought they were actually ... pleasant? In some sense. But then I find Cannibal Corpse pleasant so I probably have uncommon tastes (though not rare).
