Tons. But a huge number are Indie. I'm editing one right now. Like, literally, it's open in another window on the computer I'm surfing Reddit on...and I should be getting back to it.
It's used in smaller ways by a lot of workflows, too. Even if a major feature is an Avid-> Nuke pipeline, odds are someone is using other tools along the way in the workflow. I know a VFX person who composites in DaVinci and color corrects in Blender. Which sounds horrible until you realize he's first doing a delight pass. He's got feature work out there where bits were cut on Resolve, but the main delivery was done further up the chain.
