Why corner logos can age the panel unevenly
A small logo in the same corner for hours every day can age that local area faster than the rest of the screen. Over time, the corner may start to look slightly different on dark or flat backgrounds.
This effect is common enough that buyers of used OLED TVs should check corners carefully before purchase.
How to inspect corner wear properly
Use black and gray fullscreen screens and inspect each corner closely. If a logo-like shape remains in the same place on several backgrounds, it is more likely to be real retention or burn-in.
A short close-range check can help confirm whether the shape is part of the panel rather than a reflection on the screen surface.
How serious corner logo burn-in is
Very faint corner wear may not matter in casual viewing, but obvious logo outlines can become distracting in dark scenes, menus, and panning shots. Visible corner wear also reduces resale value.
The more easily you can see it during normal viewing distance, the more it should matter.
FAQ
Can a TV corner logo cause OLED burn-in?

Which screens reveal corner logo wear best?
Black and gray are usually the best first checks, with white used for extra confirmation.
Should buyers of used OLED TVs inspect all four corners?
Yes. Corner logos can appear in different places depending on the channels the previous owner watched most.
