I am not sure that understanding is 100% correct, here's why.
when I setup my HDMI connected STB on the LG UI it prompts me to select the service provider/device type etc & then runs thru some connectivity tests, i.e. it presents a button on screen called PR & you click on it to see if the STB channel changes, you can cover the LG remote with your hand & it still works, you can run the same test when it is all setup, as you describe bring up the LG menu for controlling the STB, obscure the line of sight between LG remote & TV/STB and select the menu pause or guide button, the STB will still respond, so it cannot be IR as the primary method.

I tried what you suggested & turned off CEC on the LG TV but still the STB controls (not record) worked from the LG remote/menu, that was confusing,

but then I read this article below, basically I read that CEC is an optional standard that can be implemented and exactly what features each vendor implements is again different (hence me thinking BT have not chosen "record") but more importantly HDMI does not Defacto need CEC to manage devices, its just not quite as level a playing field if it is not.

also, I believe the LG remote uses HDMI/CEC & also IR, in the case above it is HDMI but if you place your phone camera in front of the remote, spin the camera to front facing & press one of the LG remote buttons you will see the IR being transmitted.

I'm aware you have a G3, with a newer remote than my GX, so I wondered if this explained anything. So I looked at our bedroom C2, which has the new remote, and the Universal Control a little more automated than the GX. But you can insist on setting up Universal Control manually, so I tried this on the C2 with our upstairs YouView box, a DTR-T2110, and during the setup I got this screen (which I can also get on the GX, but I think it’s more indicative on this later TV):-
You will notice that it says to point the remote at the device. Significantly, not at the TV.
Which I can bear out for my BluRay player, some way below the TV and in a glass-fronted cabinet, set back so so popping the tray out doesn’t hit the glass, which require pretty precise aiming of its own remote, let alone the LG one.
(Sorry the formatting here is a bit messy, it’s defying all my attempts to fix it. How do I get at the raw HTML, or can’t I? 😢)
i have been thru that screen trying different device types, i think it’s probably the wording when it states “point at the device” & most likely means the TV, i’ll show you why.
when you click on the “next” button you will end up on the screen i have attached, it requires you to point the magic remote at the TV & specifically point the cursor over the PR button to check the STB channel changes when you push the LG OK wheel, so basically it’s impossible to point the remote at a different device to the TV.
hope that makes sense.
