I don't think synths get terribly close to the real instruments in many if not most cases.
Even with drums, where the envelope is much easier to copy, the acoustics of the room interacting with the mics -- and the bleed from one mic to the next -- leave tell-tales. Perhaps digital modeling will one day capture that as well, but it hasn't done so for me yet.
Never mind trying to emulate a drunken guitarist jumping around in the same room as a cranked amp.
