"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

hulu's live tv feature uses commercial detection to stop you from from fast-forwarding through commercials in recordings

SCTE-35 might be a better way to get rid of the commercials (normally SCTE-35 is intended for adding commercials rather than removing them), but only if that data is available (in my experience, sometimes it is, but not always). It might be even more better to just avoid recording the commercials (therefore saving disk space, and saing network bandwidth if using internet for downloading them), or to automatically skip past commercials when playing back a recording (instead of replacing them with something else). If using HLS, then you might use the #EXT-X-CUE-OUT command to detect commercial breaks, and avoid downloading them (although there is sometimes problems with audio/video desynchronization when converting to DVD format, and I don't know if that is because the commercial breaks are not recorded or for some other reason).
