I get what you mean “seeing detail in motion”, I think: if you go to a completely blacked-out room and throw a ping-pong ball containing a small light, if fix your eyes on something else (some other point of light, say) then the ping-pong ball will be seen as a smoothly blurred trail.

If you film it at 24fps with 180 degree shutter angle, you will get a blurred trail chopped into individual blurred streaks. About half of the trail your eyes see will be visible. If you keep a 180 degree shutter angle but film at 48fps, you will see shorter streaks, and they won’t look as blurry, but they’ll still occupy about half of the trail.

But if you shoot at 48fps (or 24, or anything else) on a digital camera with 360 degree shutter angle the trail of the ping pong ball will be unbroken.

This is often not practical at 24fps, because if something is still for 1/48th of a second and then move for 1/48th of a second, capturing with an open shutter at 24fps will show it as blurry for a full 1/24th of a second, rather than still for 1/48th and moving for 1/48th. The standard 180 degree shutter has been settled on alongside 24fps to produce a reasonable amount of motion blur; increasing it on its own doesn’t work. But a higher framerate with an open shutter is more akin to reality. It has not stuttering, and no detail in the motion that shouldn’t be there.
