it adds up, still Game Freak's work. At the same time, just because Incineroar got more exposure, didn't lessen Primarina's popularity any less, who's line theme behind it includes performing (singing, dancing) and has idol-esque odes mixed with the clown and opera singing ones, which is big in Japan. Also for better or for worse, those who worship it for its beauty, boners may or may not be included. Likewise, even though Incineroar might've been disliked at first, doesn't mean it hasn't been exposed for "bara material" for certain artists
Decidueye is actually pretty damn niche for Japan, the other two fit the bill more perfectly. The other two were easily to catch up and soon leave him behind.
