Neither does the windows PC here but it'll wake up when sent a Wake

If the TV has been hacked to do spying it doesn't need to do any of the
standard ways of WOL, etc.
It may just sit there pretending to be off while recording what's said
and sending it later.

The CIA/hacker decide what it does not the manufacturer and they can do
more or less what they like to hide its working.

If they have hacked the TV they may well have hacked the router too.
It could spoof another MAC address while spying so it wouldn't appear in
the routers tables as the TV but say, for example, the smart stat.

Even if you write your own code there are ways to put code into the
system without you knowing unless you code in hex. There was a
demonstration of how to get a C compiler to put code into programs
without the user knowing a few years ago.
