That's a good question, I'm wondering though, if the shutter speed on commercial high speed cameras is faster, but I could be wrong?
"A Phantom camera he uses goes up to a maximum of 1000 fps in 4K — an exposure time of 1/2000 sec with a 180° shutter speed — and the image starts looking pretty dark on the screen."
I'm just trying to find what shutter speed you can get with the Pi camera.

You can reduce the shutter time nearly arbitrarily, as long as you increase light intensity. I did place fast rotating propeller just above a 5000lm led, and did two 9us long flashes. See this image on how bright the two blades of propeller look, at both captured locations (the rest is dark, image was taken inside a closed cardbox, without flash everything was just black):

Edit: Just having a little play:
./raspiraw -eus 500 -md 7 -t 1000 -ts tstamps.csv -hd0 hd0.32k -h 64 --vinc 1F --fps 660 -r "380A,0040;3802,78;3806,0603" -sr 1 -o /dev/shm/out.%04d.raw 2>/dev/null
500 microsecond exposure (1/2000 seconds) seems to run.
