Ultra HDR photos support

[gsdgethjfjj]

Is your feature request related to a problem? Please describe.

Android supports Ultra HDR photos. Photos doesn't look like they are HDR when opened. When I somehow edit pictures (crop, filters), all HDRness is gone and Google Photos doesn't show Ultra HDR label no more.

Describe the solution you'd like

Please add support for viewing and editing Ultra HDR photos. These links might be helpful:

Describe alternatives you've considered
Like I wrote above, Google Photos supports Ultra HDR photos but it's too bloated and too Google for me.

I will look, i think it's possible to display HDR Images, but not sure about saving with gainamap

Thanks! Google Photos can crop and apply filters with all HDR features being present. I can share sample photos if it helps

I have pixel 8 on my own, so i can test it👀
