OLED Display Assembly
The graininess is caused by 'Mura' effect, a physical non-uniformity in the OLED sub-pixel luminance levels. This is a hardware-specific issue where the LTPS/LTPO backplane fails to provide uniform current to pixels at low voltage stages, resulting in a 'sandy' appearance. Replacing the full display assembly with a unit from a higher-tolerance production batch is the only method to resolve this physical semiconductor-level variance.
