Probably an earlier model. Here is my homescreen on a modern LG B9.

Ignore the wonderful garish Xbox360 "pawn shop special" stand. (I don't pay more than 50 bucks for consoles, and I really need to get a proper TV stand, yes). Anyways, none of those apps on the bottom bar have ever been installed/used. They are purely ads. I think I accidentally toggled DIsney+ open once, hence the mark (it's near my PC input). Helpful when switching inputs, that's for sure...
I don't know but they still haven't fixed it as of as recent as 10 months ago, according to reddit.

I returned it. The LG OLED has been great, but I haven't trusted it with free roaming wifi either.
That's the idea behind Roku. No nonsense media player that isn't ad filled. If I were to buy another smartTV I'd consider it running Roku a plus.
