All of your blocking still doesn't change the fact that your LG TV is actively trying to scan your local hardware, gathering IP-addresses of devices, wi-fi names and signal strengths, creating digital finger prints of the audio and video projected on your screen, recording audio through the internal microphone, even when the TV is in standby or without an internet connection, saving the collected data locally and uploading to LG Ad Solutions as soon as the TV is connected to the internet.
But it's never connected to the internet, not even for software updates. If the TV isn't connected to the internet there's no reason to update it, assuming the TV works as expected.
It's a trade off I guess. I use Home Assistant to control TVs, so kinda need the access.
Yeah which is why its imperative that you _never_ connect to the Internet.
