Doesn't mean much the only people agree with you are die hard naruhina fans. There bias is pretty straight forward
Well Hanabi did mopped the floor against Hinata only if you stick with the context alone aftermath conclusion in the manga but we don't know the full story prior of what went down in the ritual between the two so the rest are just pure speculation and headcanon. However when the Anime and DB backed up the claim that Hinata was holding back in one of the instance, then it holds more accountable and substances than your argument despite classifying as
"fillers" which still overshadows the doubt that Hanabi won the sparring due to her sister
"incompetence"
Back then, the majority of the fandom understand The whole canon vs Fillers used to be the norm of Naruto however this is not the case with Boruto when there was up-rise with both anime and manga as canon due to Kishimoto and Kodachi contribution to the franchise.
Hinata and Hanabi EP are no ordinary "fillers" but it's also serve as promotion to Naruto the Last Movie which all ties in to Boruto Anime. Not only that, but this so called filler helps to establish the foundation of Hanabi as a character which seems to be more integral to her story knowing that Kaguya Backstory in the Shippuden filler was also briefly referenced just recently in the Boruto Anime.
My point here is that anything in Boruto can be taken as face value whether you believe its canon or filler.
