Thank you for sharing! I have the same TV (85" QN90B) but original factory motherboard.
Seems not worth the risk at all to update, so I will just keep going with what I have.

The 85inch models are using different type of panel. My 65' QN85B uses APS panel while your tv uses VA panel. maybe that's the case why. I have tested everything yesterday and it seems ok. 

Although i still have warranty i hope everything will remain the same.

Anyway it seems to be a software glitch for sure.

Yeah don't update just dimms your tv breaks local dimming and makes the hud a bit faster... And still no hue sync app

Yes that's true the 85 inch model have the better panel but I think it's regardless of the panel type it's again just a silly software big that can't really be reproduced...

I am just happy that this appears while I'm having guaranty because it just really appeared out of no where...

A technician will look at it and repair it so If I don't forget it I will keep you up to date what the problem should be (because I got a mail that says they bought all the new hardware things and will contact me if it arrives)

Mine updated to 1602 overnight, without the auto update function turned on..

Something felt a little off, I felt like there was more blooming than before.

So I checked if it had updated without my permission, and it did.

But the backlight seems to be working ok as far as I can tell.

Not sure what causes the blooming to be so apparent.

Mine said to update while i was watching yesterday. There were 3 options. To update now, update later (after the tv restarts) and do not update. You probably selected update later. I did not update and it still is on 1520 today. Everything is working great.
