That is a blue light filter, so you shouldn’t need a third party filter. The science just isn’t out there to show whether or not it helps with sleep, though. It might help, but other things like not using screens within a couple hours to bed and not using phones in bed has better outcomes.
I use it, but I don’t notice any difference in my sleep quality
Maybe because the whole “blue light in displays” has no real effect on our sleep

I can’t say I notice any difference, either**, but it does seem like it reduces headaches for me and makes it easier on my eyes in low light.
** I’m an insomniac, so “better sleep” is often “any sleep I can get” lol.
