"Filler" can be canon (Kakashi Gaiden, for example), and filler can only exist if the anime adapts the source material, which Boruto doesn't. So not only is non of the Boruto anime filler, it's also all canon, since the author(?) of the manga himself connected anime and manga in a tweet last year or so. Filler is simply content used to fill in extra time and seemingly doesn't add anything to the overall plot. If you can remove it and it changes nothing to the plot, then it's probably filler. It also doesn't only exist in anime as western media also uses it. The anime doesn't need to be adapting anything for filler to exist. I didn't deny the many travesties of this anime are canon.

See, but that's the problem: The anime precedes the manga content. It's like two straight lines that are just waiting to be connected (which will take place when the anime starts adapting the manga). So if you'd remove the anime, you'd remove content, in our case. So yes, the anime needs to be adapting something for filler to exist. If an anime starts out with adapting something else than the source material and never changes that, it's not filler. If it starts with adapting the source material and then creates new material so that the source material has more content to adapt, the new material is filler. Right now, this is the state Boruto is in vs how it usually works: https://www.autodraw.com/share/QEWRF8OJO289

And no, I don't have a link to that tweet at hand. It should be somewhere in the Consensus Track board, I posted it.
