I do not agree. Yes, Elsa and Anna (and the rest) have the same flavor as the movie version. Nothing is being changed about them. But as far as Once canon is concerned, all we can truly say about Anna and Elsa is that their Parents died in a storm trying to get to Mist Haven (aka the EF), Anna is engaged to Kristoff (which is not necessarily Frozen canon, by the way), there is some sort of relationship between Kristoff and the Rock Trolls, and that Elsa was trapped in an Urn and stored in Rumples secret vault. It is strongly hinted that Elsa has issues controlling her magic, so we could add that as well. The rest of Frozen, though, can not be considered canon (in the Once universe), unless those events are brought in through story reference or flashback.
