I can see a future where Chrome will use the system resolver for everything except Google's advertising domains, and those name resolutions will be impossible to block because they're going to a Google IP that may also serve services you want. Maybe Chrome would get called out for this change and they'd back it off.
But I doubt that a smart TV that does this would get called out, and even if they were the response would likely be "Oh, that model is three months old and we don't do firmware updates, sorry."
Google already makes blocking individual services nearly impossible. Want to give kids access to Google Classroom? Auth is done through google.com so now search is unblocked. What about Google Docs? You’ve just opened all of YouTube as well.
That's not a good argument to block DoH, since once apps or devices would start doing that, they could just as easily start hardcoding the IPs instead.

That's already been the case for years, and is why DoH was invented in the first place.
Chromecasts hardcode DNS to 8.8.8.8, so people would redirect that traffic to their PiHole for adblocking.
To "fix" that, Google introduced DoH, which is why adblocking on chromecasts is significantly harder nowadays.

Just had a nice reminder that all of YouTube is accessible from Google Classroom as well.
