An 8-bit and 16-bit PNG side-by-side

SUMMARY

Image files with bit depths higher than 8 do not have previews/thumbnails regardless of settings. 
See the attached screenshot for a 16-bit screenshot from mpv and its converted 8-bit counterpart next to it.



STEPS TO REPRODUCE

1. Create a 16-bit color image. mpv with screenshot-high-bit-depth=yes can create one or you can convert an existing image with imagemagick:

convert image.png -depth 16 output.png

OBSERVED RESULT

Preview is not displayed.

EXPECTED RESULT

Preview is displayed.
