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

Why Can't I Install the update over USB? I using mac, and when downloaded the file is already extracted and I cant extract further. If I put the update on the USB drive, and try to update the TV says no update for you right now etc. How did you install this?

Something is not right with that file you've provided, it is missing the FLAG. file which is why I can't install it.

If your screen looks darker than it should check your eco settings. For some reason after update ambient light detection was switched back on for me and once turned off brightness came back up. It now looks like it would if it didn’t dim down.

It is only for q95t European version.
You have to extract and "put the main folder on the root" then try to update.

My US 55" Q80T was missing the FLAG file also, but the updater asked if I wanted to search the USB Drive, and it worked.
I went through and checked the ECO options. Switched them on and then back off, and the screen is still dark with HDR.

Eco settings OFF. But this new update add more blacks to everything on game-mode which looks good
