xv and display don't need to be installed either. In fact, xv is
unlikely to be installed (it's non-free (shareware) and hasn't been
maintained in ages[1]). Display is part of imagemagick, which is also
optional (though quite likely to be installed - among other things CUPS
depends on it). And display isn't very useful either (for example, there
doesn't seem to be a way to scale down large images to the size of the
display).
OTOH, xdg-open is part of the free desktop specification, so if you have
any kind of linux desktop, it is very probable that you have xdg-open
and that it is reasonably configured.
I agree that show should call xdg-open preferentially and maybe fall
back to display. And of course silently ignoring a documented parameter
is clearly a bug (if it's true - I notice that the Pillow docs don't mention
that parameter and the original PIL seems to unmaintained).
