This is definitely the 100% canon true ending of the game, even if the devs forgot to put it in there (making games is hard,sometimes you miss some details).
Perspicacious readers may have noticed that the Knight has two arms here. That is also totally canon and not an error on my part (to err is human but I’m mostly crustacean and there hasn’t been a single recorded instance of a crab being wrong about anything).
