is bleach: thousand-year blood war (bleach: sennen kessen-hen) episode 19 filler?

In the Soul King Palace, Tenjirō Kirinji stands on the Vestibule Road with Senjumaru Shutara and Kirio Hikifune, where he announces that the Royal Guard are ready and tells Ichigo Kurosaki that he should be too, prompting Ichigo to step forward in a heavily-layered garment and confirm this. When Ichigo questions if he is not wearing a few too many layers, Senjumaru notes that the clothing will allow him to break through the 72-layer barrier between the Soul King Palace and the Seireitei.
