In this particular case, I would say that the call is not conventional, because
the suit implications are part of general bridge knowledge. A player who bids
three suits in the face of partner's attempt to play NT must be short in the
fourth suit; with 5332, he would either pass or raise NT. The fourth diamond is
also an inference; with six spades, he would have bid 3S or bid 2S the second
round, and with four hearts and only three diamonds, he would have bid 2H, not
2D, on the second round.

Hearts are the relevant denomination, because this bid's primary message was
about hearts, and the holdings in the other suits are secondary inferences.
This applies even to clearly natural calls: 1C-1H-2D is a bid everyone agrees is
natural, but it also carries information about four suits; it shows at least
four diamonds, longer clubs than diamonds, and denies four cards in either
major. If it is out of turn, the penalty applies only to diamonds, even though
the 1C opening could have been three cards (two in some styles) without the 2D
bid and is now known to be five.
