Why are photos taken with the Xiaomi 15 Ultra brighter when viewed in Xiaomi Gallery than in other third-party apps?

Thank you for your support of Xiaomi products. The Xiaomi 15 Ultra has undergone strict professional inspection before leaving the factory, so you can feel confident in the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
When the ultra-dynamic display function is enabled, Xiaomi Gallery significantly enhances your viewing experience by showcasing brighter photo content in a way that brings out more realistic details and restores the visual representation of the image to its truest form.
When viewing pictures in the third-party apps, if you feel that the display is dim, you need to adjust the screen brightness according to the surrounding lighting conditions. Especially in a brighter environment or when viewing photos with a lot of light elements. Try different brightness levels for a more pleasant and comfortable viewing experience.
