To be honest, looking at the PiHole logs the TV itself hasn't tried to do much of anything. The apps on my streaming device (namely Netflix before I uninstalled it) tried, but the PiHole always caught it.

At this point I wouldn’t rely on PiHole DNS logs alone. You’d need to check network traffic from the device in general, it could use DoT/DoH.

And I suppose there’s the even-creeper Amazon Sidewalk: https://www.amazon.com/gp/help/customer/display.html?nodeId=...

I hate sounding like I’m wearing a foil hat but there are a lot of easy ways to get around trying to neuter smart devices now.

And DoT/DoH don't even add new capabilities, it's been possible to use a VPN to a popular shared hosting provider (e.g. AWS) to hide traffic for a long time before DoT & DoH became standards.
