This issue is characteristic of burn-in, which is a common problem with OLED displays. It occurs when there is prolonged exposure to static images, causing some pixels to degrade more quickly than others, leading to uneven wear and a noticeable persistence of images or discoloration on the screen. Backlight bleed is associated with LCD panels, not OLED. Dead pixels would display as black spots on the display and wouldn't be affected by static images. Image persistence is a temporary issue often seen in LCD displays and differs from burn-in as it can usually be resolved by allowing the screen to display a moving image for some time.
