ICC profiles of photos are ignored. If photos have an Adobe RGB profile, they are displayed too pale. All previews are displayed incorrectly: in Files, Photos and Viewer. The previews/thumbnails should have the same ICC profile as the original photos. Until now, the preview images lose their ICC profile.

Here is an example in Viewer. The first photo has an sRGB profile. For the second photo, the profile of the photo was converted to an Adobe RGB profile.

Background: More and more cameras are recording with the Adobe RGB profile, which is significantly larger in terms of color gamut. If photos with an Adobe RGB profile are used in Nextcloud, they are displayed incorrectly.
