AFAIK, color profile management is not supported by the current
version of FOP.
Does your PNG contain transparent parts ?
We had about the same problem, with cockpit screenshots appearing
"dull" while the original PNG obviously had brighter colors.
It is an extremely complex topic, I spent weeks trying to find a
solution to such problems and at the end, on a suggestion by Jeremias
Maerki, we simply removed the transparent parts and that solved our
problem (but maybe it does not solve yours).
I believe there is only one color profile in the PDFs generated by
FOP, and IIRC the corresponding FO tags as specified by the standard
are ignored.

Hi everybody,
I have a problem when inserting PNG files into a PDF using fop. My
PNG file has a color profile "Dot Gain 15%". The PDF contains the
same png file, but the color profile is suddenly "KODAK Grayscale
Conversion - Gamma 1.0". And, as is clearly visible, the image in
the PDF file ist brighter than the PNG. Can anybody on this list
enlighten me on why the color profile is changing or how I can
prevent it?
The PNG file and PDF file are attached, if you want to recreate the
PDF, here's the fo code:
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format";>
<fo:layout-master-set>
<fo:simple-page-master page-height="1cm" page-width="1cm" master-
name="main">
<fo:region-body/>
</fo:simple-page-master>
</fo:layout-master-set>
<fo:page-sequence master-reference="main">
<fo:flow flow-name="xsl-region-body">
<fo:block>
<fo:external-graphic content-width="1cm" content-height="1cm"
src="imgTest.png"/>
</fo:block>
</fo:flow>
</fo:page-sequence>
</fo:root>
