I agree with OP, the speed on the internet coming into the residence should display on the TV's webpage when the speedtest.com or fast.com or Ookla.com is entered into the LG browser from the TV's homepage.
I get 400+ Mbps from Spectrum. I watch on a OLED 77C8PUA. I have Apple TV, TIVO BoltVox-Spectrum Card, and direct ethernet from my Netgear switcher that gives the whole house 400+ Mbps anywhere, even WIFI.
On the OLED, I see 9-32 Mbps ethernet wired, 25-52 Mbps wifi. Wifi in reality should be lower. I still get buffering and that brought me to use my extended warranty to have a tech come out to check the set.
This tech tried changing the MOBO only to find out that is was a dead board. Although, he did change out the WIFI card. When reinstalled the same speeds were recorded from the LG homepage browser.
I would like a justification from an INTELLIGENT LG tech to tell us "what's up".
