While it's true that a biological eye doesn't really have a defined "framerate" like video sensors do, the examples you're providing don't really show that. Sensitivity to very short stimuli doesn't prove temporal resolution in the sense that's applied here; what you want to be looking at is flicker fusion instead. As a cheeky example -- still pictures have approximately zero frames per second temporal resolution but would be able to pick up that 2.5ms plane if their sensitivity was sufficiently high... Measuring ERGs (electro-retinogrammes) indicates that our photoreceptors can't really resolve luminance fluctuations above, at the very limit, 70-80Hz. Even Drosophila's high speed cascade doesn't really modulate beyond 200-250Hz. I'm really doubtful about those claims.
