If I were going to play chess against Magnus Carlsen I’d definitely study his games with a computer, and if that computer found a stunning refutation to an opening he liked I’d definitely play it.
Conditionally on him continuing to play the opening, I would expect he has a refutation to that refutation, but no reason to use the counter-refutation in public games against the computer. On the other hand, he may not want to burn it on you either.
