For the video simulations you're suggesting, they would have to slow everything down for us to see the difference, which would kind of break the realism they showed until then.

Also, the glowing trail thing would be a great way only for creatures like us humans, with slowly refreshing visual brains to handle information coming from faster refreshing retinas. But I have to imagine cats have their brains appropriately tuned for the refresh rate if their retinas and see movements clearly, with great detail in the time dimension.
