I bought a Q80T a couple of days ago and have noticed a really annoying issue when using the tv with the combination of HDR and game mode.
I'm fairly certain this is a software bug in the TV since I can reproduce this issue with 100% accuracy, and it happens on the dot at the same moment every time. It's basically on a timer.
Basically when the game is displaying a HDR signal and game mode is enabled, exactly after 6 minutes the brightness of the TV suddenly drops by around 20 (50 -> 30). The value of brightness setting doesn't actually change however. Messing with the brightness setting does not restore the brightness to it's original state, but changing the local dimming setting from standard to low and then back to standard does. Switching game mode off and then back on also fixes the issue, but then it happens again EXACTLY after 6 minutes (I've timed this with a stopwatch).
Has anyone else experienced this issue? Or can someone maybe test this on their TV to see if you can reproduce it?
Exact repro steps on how I can reproduce this 100% of the time on the PS4 Pro:
Some other notes: The PS4 has a screensaver that basically dims the screen if it is idle for a while. This is not the cause of this, this happens even when the console is in active use and the brightness can be restored temporarily by changing the local dimming setting like described above. I have not managed to reproduce this issue with game mode off, so it seems to be related to game mode.
Software version: 1304

Checking in here, played a whole online match of 2K21. No dimming when it would happen multiple times in the last firmware.

Yeah, happened to me. Took two downloads for it to finally work.

Also, to those not using a traditional USB(I'm using an external SSD) format it to exFAT. NTSF will not read on the Samsung tv. That was my problem.

I have upload photos of the local dimming performance of the new update on this thread

So, I turned off the TV. Took a nap. Came back. Turned on VRR. The screen is very very dark again.

I have UK Q95T 55" and the update file doesn't seem to work for me, keeps saying there are no new updates for me at the moment as it checks my USB drive.
