Why is the display of the Redmi Note 13 Pro 5G partially uneven in color or has an overall color cast?

The Redmi Note 13 Pro 5G has undergone rigorous inspection before leaving the factory to ensure it meets Xiaomi's specifications, so you can use it with confidence. With OLED products you can notice slight variations in color and chromaticity, this is because each pixel of an OLED display emits light from organic materials, and the refraction of light at different angles can cause differences in color and brightness, which is a characteristic of OLED and is normal.
To improve the visual experience, you can adjust the settings by going to [Settings] >> [Display & brightness] >> [Color scheme].
