is one piece episode 750 filler?

Luffy, Bartolomeo, and Desire confront Bill, who mocks their dreams of reaching the top of the New World as childish. Bill reveals to Desire that he used everyone in his Silver Pirate Alliance to give him wealth so that he could live the most luxurious life in the world, and questions whether she really intends to defeat him and if she really believes she is stronger than him.

Bill taunts Desire, and she starts rushing at him in anger, but Luffy suddenly flies in front of her with Gear 2 activated and punches Bill into a cliff face.
