I think is clearly png. Moreover ristrettro stopped to display all 
images I have tested so far.

I got so far as cache_get_mime_type_for_data in glib2.0-2.58.3 in 
xdgmimecache.c not finding a proper entry and then XDG_MIME_TYPE_UNKNOWN 
(=application/octet_stream) is reported. And there is obviously no 
loader for this fallback ;)
