do you happen to remember around what part of the podcast this was? just a ballpark guess
He's actually done shouts for this TV multiple times in the past as well.
I am also pretty satisfied with my TV so far. For reference, I have another 55'' Samsung TV (4K but not HDR) and I find the TCL has better picture quality in even normal content. But it may also be due to the fact that I've set up a theater like location for the TCL and the Samsung is in the room under harsher conditions and lighting.
Gotta admit though, HDR takes a lot of calibration per-game to get that "sweet spot" and as others have said, often times the results are a little bit darker so I have to use the "Brighter" settings and color temp to Normal. I just can't get used to how yellow everything looks on the Warm color temperature.
I also use the TV as a TV, for PS4 Pro and also a gaming laptop, so I'm getting good use out of all 3 HDMI ports and it's been great on all three. The only negative I've noticed is that if I have local dimming completely off, in completely pitch black areas you can see the white/grey color bleeding slightly in the extreme edges of the TV. However if I have the local dimming to even low, it is completely eliminated. I usually keep the local dimming on either Low or Normal depending on what's on.
