In this case, they aren't.
I woke up the other day to a notification that my LG monitor driver was installed, with a little window on how to use the on-screen crap.
Absolutely useless, since the buttons for the monitor are right there on the bottom of it, and probably easier to use than the software.
Indeed, our Windows 11 offline Steam box also needed to disable LG & Switch App in taskmanager, and set LG apps to manual start in Services.
Apparently the 3 applications have some sort of screen partitioning/sharing capabilities, but it is still unclear if the LG App was remote access or not.
So far, LG is earning a lot of justified bad press. Should have returned it when I had to turn off the screens power-save mode to get it to stop fading out randomly. =3
