Why does the brightness flicker when the Xiaomi 15 Ultra enters or exits HDR videos?

To restore realistic visual experiences and enhance the HDR experience, the Xiaomi 15 Ultra automatically adjusts the brightness appropriately when playing HDR videos. The slight flickering during the brightness change is a normal phenomenon in the usage process. Please rest assured and use it. Thank you for your support.
For your reference, here are more details about the screen flicker:
1. When playing HDR videos, the display needs to readjust to a different dynamic range and color space, and the switching process will cause the screen to flicker temporarily;
2. When the phone enters or exits HDR videos, the system automatically adjusts the brightness. If the automatic brightness adjustment changes greatly, which will cause the screen to flicker temporarily during the transition.
