It's not canon, because these scenes literally do not exist. Lmfao why is this so difficult for people to understand?
Their abilities may be canon at best, but the feats and interactions in these movies never happened. Where tf does this timeline even work out according to canon dkm, Strawhats are in wano, before wano they were in WCI and so on so forth, did they make a pit stop somewhere to go watch a wannabe hatsune miku concert? And this has to be during or after Wano since nika is involved? It's fanservice to be enjoyed not analyzed.
