The problem with my test png image is that it has transparent parts
that need to be displayed with a light color so that one can
recognize the nontransparent dark parts.  But the image uses fully
transparent black as background.  The behavior in such a case is not
strictly defined by the png standard, see

https://sourceforge.net/p/png-mng/mailman/message/36747189/

Emacs displays such fully transparent background with its original
color specified by the image.  But I believe it would make more
sense if emacs used instead a background color that the user can
choose (the background color of the frame), similar to, for example,
eog.

Should I submit a separate feature request for this?
