Thats funny, all the crew were from P.& O. (see P.& O. flag on the bow), all they need to do is take the Princess Cruises logo off the funnel and paint it P.& O. buff, it's a pity she's been renamed because her legacy is of course that she was launched by Princess Diana they took her name for bigger & better! lol
Artemis in Greek mythology, the goddess of hunting and the moon, and of childbirth. She was the daughter of Zeus and the sister of Apollo. Roman equivalent Diana. Hence there is possibility of a connection with the new name.
