I'd be surprised if it doesn't frankly. The blue-light effect on the circadian is well documented science. Don't think anyone is challenging that.
...and turning on flux makes the screen decidedly less blue-ish even by a non-scientific eyeballing so I'd be very surprised if it doesn't check out on a broad level.
Whether it delivers the tangible results promised is a different question.
Broadly speaking I've noticed a correlation between late screen time and bad sleep (or rather falling asleep).

Your observation could be due to the placebo effect. That's why a study is warranted. A yellow post-it could have similar effects if everybody constantly said that having a post-it on the display frame prevents circadian rhythm disruption.
