is one piece episode 736 filler?

The people on Dressrosa and the neighboring islands receiving the Marines' broadcast are still bewildered by Admiral Fujitora's prostration before Riku Doldo III. Doldo tells Fujitora to get up and asks if he really wanted the whole world to see this, but the Admiral refuses, saying that he left the Straw Hats to do everything in hopes that they would succeed.

The Marines had done nothing because of Doflamingo's Shichibukai status, and Fujitora wants to make it clear that this was not the Marines' victory. Meanwhile, Usopp runs through the streets with Robin and Bartolomeo, looking for Luffy.
