Missable trophy?

[xuanlong-huangdi]

I am aware that one of the purupuru finishes involves defeating your opponent near a festival platform. But assuming you destroyed all 80 festival platforms, and you haven't done the purupuru finisher with one of them, will, "Your OCD is Showing" become missable?

I do believe that if you destroy all the festival platforms without doing that particular finish it will become available automatically in the shop after destroying the last one.  I was still able to get it and I am 99% certain I never saw that finish throughout the course of the game.
