UltraHDR image sample

SUMMARY
Currently, the wallpaper module of the plasmashell doesn't show HDR images as HDR. I would like to have UltraHDR images displayed with the HDR gain map correctly when set as wallpaper or as a lock screen.

STEPS TO REPRODUCE
1. Set an UltraHDR image as wallpaper or lockscreen
2. Observe it
3. It's not shown with the HDR brightness

OBSERVED RESULT
Images are shown as normal SDR images

EXPECTED RESULT
Images should be shown with HDR highlights when applicable.
