I’ve recommended to parents to use blight light filters on iPads for their kids and their sleep has always improved. That’s what confuses me, why does that work on children?

You can't do that without altering their other behaviors. Basically a "don't think about pink elephants" situation.
Also remember that sleep quality without a tracker is very subjective and reporting someone else's sleep quality even more unreliable. Insomnia specialists often find patients who swear they never nap asleep in the waiting room before a visit.
They were young kids like 2 years old. They had no idea what I was doing with the screens. Their sleep cycle was more regulated. They started to wake up consistently around the same time and go to bed around the same time. Nothing else changed.
