Is gear 5 a plot hole? - Lemmy.world

In chapter 385 Lucci states > You learn the name of the fruit when you gain its power - so why did Luffy not learn the name of the Human-Human Fruit, Model: Nika after eating it? - or did he mean you name the fruit yourself after learning of its abilities?

They have devil fruit catalogs but often times the power/name does not have a picture of the fruit prior to being eaten. So basically once they find out what powers they have they can match it to an existing fruit.
