I wonder how much energy it take to analyze 4k images 10 times a second?

I have to think that whatever they're using this for, it could be done at a much lower data resolution.

They do this to match what you're watching to a database. Think Shazam but with video.

They find what movie, show or whatever you're watching and send it to advertisers with all your metadata, so they can match and track you from an ad impression to you visiting their site to get information and buy.

There's a lot of metadata there to match. If you access their site, for example with your phone, from the same internet connection, they can probably match the information from the TV with one of the tracking cookies on your phone, and then keep tracking you in all the commercial "journey".

This has been already discussed around here because this is one of the reasons smart tvs are so cheap right now, because they're being subsidized by advertisers. Some of the advertisers had in their sites information about their tracking capabilities. I'll try to find that link.

The answer is: Who cares? The rube who bought the thing is paying for it.

10ms is 100Hz not 10Hz.

A conservative assumption would be that they use all spare cpu time for spyware? Maybe 1-10W extra if small arm processors?
