To the best of my knowledge, there's nothing else that's realtime like this for end users?

There are other offline tests like the Harding test that are run by the content creators (and why you see the epilepsy warnings at the start of shows)

FWIW, I'm not sure if this actually would benefit cats. I'm not up to speed on feline perception, but I know dogs see at a different frame rate than humans so things that won't trigger us might trigger them differently
