I don’t think this is a particularly good refutation, since the things utilitarians mostly care about (pleasure and suffering) and the things that the experience machine is likely to be bad at simulating (minute details of quantum physics) have almost no overlap.
I would reject an experience machine even if my (reported) satisfaction after unknowingly entering one was wildly higher than my enjoyment of reality.
