Thanks for the write-up, it reflects my own impression of the video.

The video is quite a mixed set of topics mangled together, which is a pity because IMO a cleaner separation would be more beneficial to get the point across.

They should have decided to set the focus on a specific area and then present every finding around that, i.e.:

1. The Ad data-collecting platform TV-manufacturers are operating, what data they collect and how they use it.

2. The vulnerabilities of the OS in a SmartTV, and the potential issues to exploit them for malicious purposes.

3. The general behavior of the device when connected to your network, with features like voice control, App control, Smart Home etc. enabled, and how it may expose information about yourself.

All the points and scenarios in the video might be valid, but they jump between those scopes and imply that its all the same, weakening the whole investigation.

If I'm LG and forced to respond to this, I can easily focus on dissecting the voice-input topic as a mere demonstration of the feature and how rooting the TV beforehand just showed the local process of handling it, steering the narrative away from the (IMO) much more important topics...
