Why are the original photos of the old mobile phone lighter in the Gallery after switching to the Xiaomi 14?

The Xiaomi Gallery employs wide color gamut, coupled with photos taken with Xiaomi's native Camera APP, which aims to deliver a more realistic visual experience. We encourage you to use the Xiaomi official Camera and Gallery for future photography needs.
Changes in the color of historical photos are a normal occurrence in the industry regarding color management. However, photos captured with the Xiaomi Camera APP will not experience this issue.
If you wish to enhance the display of historical photos, you can try adjusting the settings as follows:
Go to [Settings] >> [Display & brightness] >> [Color scheme] >> select [Vivid], or utilize the custom color adjustment feature in Advanced settings to enhance the viewing experience.
