Users who see the grain generally report that it is most noticeable in dark environments with the display set at a low to medium brightness while viewing content with gray or muted colors. Some have compared the effect to a photo taken on a high ISO setting that has visual noise.

Whether this is a genuine display defect is hard to say at this point. OLED displays in general can exhibit a visual grain or a "screen-door effect" due to several factors related to the design and manufacturing process.

The individual sub-pixels in OLED displays can vary in size and shape, contributing to an inconsistent, uneven texture or graininess. This is usually more noticeable on larger displays. Variations in the deposition of organic materials can also affect the uniformity of light emission.

OLED displays also control brightness at the pixel level, and power management techniques can lead to minor variations in brightness across the screen. This is sometimes noticeable as a grainy effect, particularly in low-light conditions or when displaying uniform colors.
