Sure, eyes dont have a “global frame refresh” like computers do. That’s why we can tell the difference between 24hz and 60hz video. Every eye cell is excited independently and continuously.

Still, there’s a physical limit for frame time where 99% of humans wouldn’t notice a full screen flash 99.9% of the time. Being able to shake your head around with a 1000hz vr headset and not perceive and motion blur from sample and hold seems pretty close to that limit.
