Their full answer illumniates what they are doing

> ACR in LG TVs does not collect or store screenshots, screen images, screen recordings, or video recordings from the TV. Instead, it uses audio fingerprints generated from content audio using the TV’s internal soundboard (not a speaker) to identify the content being viewed.

So based on the fingerprint they know what content is being displayed, but they can say they're not recording your screen.

I work in marketing. LG literally offers to target people who've recently watched a competitor's ad. When I asked how that's possible the sales guy openly admitted that "they know what's showing on their panels."

Maybe he just said that to make a sale, but yeah the fact they offer that targeting alone is quite telling.

All these companies are probably lying to some degree. There's no reason to trust them.

They say in their answer that they use audio fingerprinting for ACR instead of screenshots. Are you certain they are lying about this?

note they didn't say "LG TVs do not…" which might indicate whatever lawyer drafted this found a vaguely legally plausible way to attribute that to something other than ACR

Ballsy for LG to deny anything considering what started all this.

they don't collect the screenshots, they store a fingerprint of the screenshot. They are not lying. Also they do store but not collect.
