I'd guess that you can equate "screen time" to "smartphone use" in most of the population but here. Similar to what people are using the screen for.

To include so many variations of screen would complicate a lot the study, and without a prior about why it should matter, you are probably safer starting with something more homogeneous.

I'm fairly confident this is not a safe assumption.

How so, though?

That's not very scientific, is it? There's no prior as to why it shouldn't matter, which is what the authors seem to think.

A huge number of people are professional screen-users. Almost every office job, and quite a few otherwise. I probably spend more time on my work laptop than my phone, and I'm pretty bad for using my phone a lot.

Presumably you don’t think that all the white collar workers who aren’t in tech spend all of their work-hours scrolling tiktok/etc.?
