Capacitive coupling still counts as galvanically isolated. Dielectric resistance of typical Y caps is in GOhm range, so that's basically galvanically isolated, unless you're some kind of purist. You certainly will not be able to feel that. Reactance of a typical Y capcaitor at 50Hz is in the range of single unit MOhm so even that does not cross perception thresholds of most individuals even at 230 V. But it may for some, I guess.
