Regardless of the content on the screen, the screen time is bad for kids.

Even desiring pixel-represented "data" for this fact that is obviously observable irl is itself perhaps a result of excessive screen-time, leading to spreadsheet brain, but I can gratify you with these studies: [1], [2], [3], [4], [5]

Of course, no study will exactly disprove the claim that there is some possible content that is a net positive for kids, akin to how no study can prove that unicorns don't exist. But this is exactly the kind of brain-melt, culturally destructive kind of thinking you could expect for demanding "data" for every obvious fact.

Screen time is simply bad for kids. Don't give your kids a screen. Give them a ball, a stick, a book, etc
