Why is the color displayed differently between the upper part and lower part screen of the Xiaomi 15 Ultra?

If you’ve noticed a difference in color or chromaticity between the upper and lower parts of your Xiaomi 15 Ultra screen, this is due to the nature of OLED displays. OLED screens, which are used in the Xiaomi 15 Ultra, are known for their deep contrasts and vibrant colors, but they can sometimes exhibit slight variations in color temperature or brightness across different areas of the screen. Xiaomi performs strict professional inspections before every phone leaves the factory to ensure the overall quality and functionality of the display.
You can try to adjust as the following settings:
1. Go to [Settings];
2. Tap [Display & brightness];
3. Tap [Color scheme];
4. Choose [Vivid (recommended)].
5. By adjusting the position of the point in the interface ball, change the preference of the screen display effect.
