I don't think this is accurate. I'm fairly sure Apple Pay uses tokenization, so the merchant/merchant bank never sees the actual card details. The only party in the transaction who knows the actual card details is the issuing bank.
You are right, I was mistaken. The DPAN is the tokenized card number, and that is the only account number an acquirer will have. My experience seeing both in the auth system log was from the issuer side.
