Comment (by cehoyos):

 Replying to [comment:4 kurosu]:
 > ffmpeg doesn't parse the bKGB chunk that contains this information as
 indeed you can't have both transparency and a background at the same time
 in ffmpeg.

 Yes but the sample in question does not contain a bKGB chunk and is still
 displayed better by many / all other programs that support displaying png.
