Have a QN90A 85" NEO QLED and it is getting these local dimming artifacts while navigating menu items within Kodi connected to Nvidia Shield.  Artifacts glow about a second then disappear and only happen in standard or high local dimming setting.  It might also happen in low but its not noticeable.

Otherwise, its a great TV but i have to wonder if this is noticeable here, where else is it present compromising picture quality.   i was debating between this and an oled and went with this given the stellar reviews and larger size.  my choice now is to return it or wait and hope this is something that can be addressed in a firmware update.  btw, its on latest 1560.5 firmware.

OLED is the way to go. Any back lit or edge lit TV will be susceptible to clouding or edge bleed issues, and now local dimming issues.

I saw this and showed it in a video:

Samsung needs to tweak their local dimming. They need to speed up the transitions.

If you go OLED like the other person suggests you will see a similar effect called image retention. The problem there is that cannot be patched by a firmware. All OLEDs have some form of image retention that fades away.

Give it time and I'm sure Samsung will make improvements to the local dimming.

only worry is that it will be something that can be addressed by software and not a hardware limitation.

You won't see distracting image retention on OLEDs in normal content. Not even visible in dark games with HUDs in HDR.

You don't see this in "normal content" either. Its in menus.

You have a higher chance of image retention in watching sports or long sessions of gaming with huds, etc.
