Unsurprisingly it would appear that the sets (or at least those images) are based on the Netflix show instead of on the films.
Why do you think that? (have seen both movies but not the show)
It looked as if the boxes (at least those preliminary ones) had the
DreamWorks Dragons title written on them. That's what the show is called now.
Also, the scenes do look like they could be from the show, and - with Playmobil having its own Netflix presence now - there might be some kind of related marketing negotiations.
