I mean holo-wife could not do the telepathy deal either.
But okay, how about if when he goes through Pon Farr he obviously has NO idea what is going on, goes psychotic and kills a bunch of elves. That would be what leads to his banishment, deep into the program.
A vulcan who thinks he is an elf would not think that he's supposed to have telepathy and thus would not miss it, when he first encounters a real person, he might discover telepathy for the first time.
That's so true. His telapathy would have NOTHING to be aware of.. other than perhaps complete absence of personhood from the holograms.
I predict the Vulcan would decide he must be a superior being because of this. Don't forget it's not all about ears.. I doubt the Vulcans and the Elves bleed the same color so early on he would have become aware of his difference.
