Why is the screen color of the POCO X6 Pro uneven at low brightness?

Thank you for your support of Xiaomi products. The POCO X6 Pro has undergone strict professional inspection before leaving the factory, please feel free to use it. As the limitations of OLED display materials, the display will have slight color changes at different brightness, which is a normal phenomenon. You can adjust the screen color according to your preference.
For your reference, here is the method to adjust the screen color:
Go to [Settings] >> [Display & brightness] >> [Color scheme], you can adjust color temperature and change the screen display effect as your preference here.
