These guys that are throwing up all kinds of slides to see a line here or there and then returning 2 or 3 sets are one of the reasons why some sets are so expensive, manufactures have to build into their costs all these nonsense returns.
If you return a set for a defect that is seen during normal viewing well than I have no problem with that.
Trust me, I wasn't looking for it with slides at all. I noticed the banding and giant dark patch without going on a hunt for it. It showed up, and was easily noticeable during normal viewing. When basically half of the screen is pitch black, while the other half shows a dark gray, you notice something is off. The banding only took a couple of camera pans, not even a very dark background was necessary.
Only after I noticed all of this in actual content, I put up a test pattern. You can also use the built-in 20p white balance 5 IRE pattern the TV has. No need for external sources at all.
For example: I started S01E01 of Fargo on Netflix. A few seconds in and you can easily notice all of these faults without knowing they exist beforehand. Or S04 of Better Call Saul, and there are lots of other instances where it's easily noticeable.
Or just start the Netflix app and sometimes a gray screen, with some cubes on the right hand side, shows up briefly. You can notice it on there as well, because the top right corner is darker and discolored.
Brighter grays and also some colors still exhibit a discoloration in the top right corner.

The frequency of this recurrent problem 3-4 years after its debut shows me what a dumpster fire the manufacturing process continues to be. The 2016 effort to attain improvements that year clearly couldn't be maintained without the sets being in the $5k-8k range.
I know from others who ordered the same TV from the same retailer at the same time as me. I've seen a photo of a 5% slide on one of those other OLEDs and it looks pristine. No dark patches at all, perfectly uniform. Maybe just the tiniest hint of vertical banding, but it's so minor you would probably never notice it even in the most demanding scenes. The others have claimed similar uniformity, alas no proof. I just had the worst luck apparently. As always, sadly. I'm sure mine is not the only dud, but it sure feels like it.
