Why does the screen flicker when viewing photos in Xiaomi Gallery on the Xiaomi 15 Ultra and lowering the brightness?

Thank you for your support of Xiaomi products. The Xiaomi 15 Ultra has undergone strict professional inspection before leaving the factory, so you can use it with confidence.
Xiaomi Gallery has an ultra-dynamic display function, which will enhance the photo effect when previewing large pictures, bringing you a real visual experience when viewing the photos you took in the Gallery.
To protect your eyes and ensure your experience at low brightness, the ultra-dynamic display function will be temporarily turned off, and there will be a brief flicker. If you would like to continue to experience the HDR function, you can try to adjust the brightness bar to a higher brightness.
