some TV/smart devices have a baked in DNS...and using 192.168.1.1/router internal DNS causes latency...as simple as that..was it mentioned on the link i posted too..i guess...

maybe the TV considers it a rebind attack and will not allow it?

i was able to force my samsung 2019 smart tv to use my Pi-hole by manually configuring a static IP & DNS so it should work for you, pretty sure Samsung hard code google dns so need to manually enter DNS server to bypass, well seemed the youtube app is hard coded at least.

yep setting static IP & DNS on smart devices always helps...I set it on TV's/smart devices for the same reason, Philips, Samsung and Sony TV i've no problem with setting a foreign DNS, like either my router DNS or 9.9.9.9 most of the time...
