Will check around the 100hr mark, might run a manual pixel refresh and see if there is any improvements.That's bad actually; like mine but mine has dark patches in the middle instead of one side. You might or might not notice it in content. Dark panning shots are the most problematic.
Give it time though. It can improve dramatically sometimes. 50-60 hours at least. Then you can try a manual pixel refresh. It didn't help with mine, but I'm Reddit megapost, some people have had dramatic improvements.
The new Panel that you got, was that from the Retailer or LG?
How did that procedure go?
