I understand. You have to know that, right now, they are both focusing and discussing about the manga and the anime and im sure they are adding things along the way. For example, Boruto never displayed Jougan in the manga which he should since manga should be canon and ahead of the anime since it was introduced first but instead it was shown in the anime first... or maybe its just a hint, but it should be the other way.I just acknowledge official statements from the authors on the canon. So far the Academy Arc, the Mist Arc, and such have been referenced.
Granted they are the only two official arcs of the story so far. I'm assuming we'll have one more big arc before the Chunin Examinations, and then afterwards the discussion of canon/filler will be over since they'll be adapting the Manga content outside of the few random ass filler episodes they throw in.
Unless they continue more filler arcs.
