I noticed that too. And actually, the first two episodes have the new forest, the third one the old forest, and the others from 4 on have the old forest with the same background as the new forest (with many more trees). Even the titlecards featuring old subjects (the Jolly Roger and the Clock Tower) have the renewed background.

I'd say it is worth mentioning in the trivia section...
