I really don't think its greater numbers or the panels. I think it's Sony's algorithm to equalize the voltages across the screen is probably superior since this is the cause for screen uniformity issues. For the panels that I see, there is no question that the Sony's are always more uniform. This doesn't mean that the LG's are bad since most of the time whatever is there is usually not visible with most content.
The other thing is that a lot of people, open the box, run the set for 10 minutes then post what the screen looks like and ask for an opinion, like that's going to make a difference
, not to mention that the camera makes everything look worse. I recommend always doing ONE clear screen when you get the set and then use it normally since you just don't know how it left the factory. Although this is simple and safe to do, everyone loves to keep debating and discussing this over and over and over again and as you know this has been a main topic for many years lol.
When I got my A1, I was almost in tears when I looked at the 5%. What I found out after looking at several sets in the same run at Value Electronics is that it appears that Sony must sample sets on the production line and run tests on them for a while because my set had a lot of image retention like test patterns were run. The other set's I looked at didn't have this. Once I did a clear panel, all the image retention went away and I was left with a very clear panel.
Another thing i'll mention and I have two model years of looking at LG's OLEDs to confirm this speculation, it appears that LG and probably Sony, must do some "extra" quality control for the first couple of shipments in every model year because, in my experience, the panels always look cleaner than the ones I see after production ramps up.
Not to say that there isn't a "bad" panel in any run but i'm guessing they are trying to make sure that the panels look the best they can given that they will be reviewed by professionals and the early adopters.
Finally, you will see over and over again people agonizing over which month the set was manufactured in like that's also going to make a difference
. Last year, there was never any hard evidence that one production month was better or worse than any other month except for the first month as noted above.
