Yes, why didn't you mention directly which engine you are using?
Well the backend of xelatex, dvipdfmx, has quite extended PNG
support, see the documentation (texdoc dvipdfmx).
And looking at the pdf one can see that your images are included
with different color spaces. The "wrong" uses CalRGB
2.19998]/Matrix[.41239 .21264 .01933
.35758 .71517 .11919 .18048 .07219 .95053]>>]1<504053ffffff>]
The other one DeviceRGB:
pdftex uses DeviceRGB in both cases.
I have no idea if this can be configured, you could check the
documentation or ask on the dvipdfmx mailing list.
