Why does the lock screen of the POCO X7 Pro flicker in sunlight?

Thank you for your support of Xiaomi products. All products undergo strict professional inspection before leaving the factory, so you can use them with confidence.
Under strong light, the display will show a mild reflection as the light hits the screen, causing the surface to reflect the surrounding environment. You will notice a slight color change during the screen-off process. This is a normal phenomenon. Please feel free to use it.
Additionally, you will notice a slight color change or flickering during the screen-off process or when the device is adjusting its brightness. This is part of the screen's automatic adjustment to ambient lighting conditions. As the phone detects a change in the lighting around it, it adjusts the display's brightness, which can cause temporary color shifts or flickering, especially in bright or high-contrast environments.
