How do they publish things like this with a straight face? This is not tied to the reality that I'm experiencing--you? We don't need peer-reviewed studies to tell us things that are easy to study empirically.
Please run an experiment on yourself and make up your mind.
Certainly in terms of short-term variations in quantity of screen time having little effect, and much smaller than other factors, on sleep time it matches my current experience with my son. Not that I give that experience much weight in general predictions.

I think you've confused “empirically” with “anecdotally”. N=1 testing has, in the best case, very large error bars in predicting broad population generalities. (And , in most cases, makes it very hard to isolate confounding factors.)
