That vertical bar on the far-right looks ready to stick out easily on dark/near-black panning content.here mine oled c9 after lg replace panel due to stuck/dead pixel. It look ok but still having stuck/dead pixel in some spot.

Seems like it came from the same manufacturing line as mine (still open to opinions on that one by the way. As a TL;DR it would suffice to have a look at the photos + video).
I don't get why some of these bands so well-defined with an abrupt change as if each part of the screen was made separately. I would expect gradual changes across the screen.
