The bloom and trail effect given by ambergris is replaced with ambroxan, however combining ambroxan and ambrinol does little to recreate a "real" ambergris odour. Those may thousands of other molecules, while perhaps only <5%, give a very distinctive and unique odour. It's like a rich leather bag that's been floating in the ocean for +30y - salty, marine, animalistic, musky and leathery all in one.
