Can I get some clarification on Nvidia Ultra Low Latency?

I've been looking through so many reddit threads and not only is every thread offering different answers majority of the time but half the time the users are using it alongside Reflex or in CPU bottlenecked games which just makes that whole threat moot.

So here it is, IF a game DOESN'T support Nvidia Reflex, AND is NOT CPU bottlenecked, is running Ultra Low Latency in the Nvidia App worthwhile?
