Why does the POCO F7 Ultra play ordinary videos recorded by other devices with lighter colors?

The Xiaomi Camera can take photos with wider colors, and with the Xiaomi Gallery that does wide color gamut management, it can bring you a more realistic visual experience. Ordinary videos have a limited color range, so they will show the true color of the video itself when played in the Gallery, which is also a normal phenomenon in color management in the industry.
If you want to improve the display experience, you can try to adjust as the following settings, [Settings] >> [Display & brightness] >> [Color scheme] >> [Vivid (recommended)], or use the custom color adjustment function in [Advanced settings] to enhance the display experience.
