"This setting" is called Live Plus.
it's a feature on LG smart TVs that uses ACR (automatic content recognition)
to analyze what's displayed on your screen. LG then uses that data to offer
"personalized services," including content recommendations
and advertisements.
Interesting, ill go down a rabbit hole on this, ACR to detect commercials and activate mute? Or play some spa music, then back to main audio when commercials are over, that would be pretty cool use of ACR
