Colour profiles are not usually embedded in exif data. They are usually
embedded as an ICC colour profile (in jpg images an APP2 segment - see section
B.4 of http://www.color.org/specification/ICC1v43_2010-12.pdf ). MediaWiki
currently does not extract this data at the moment.

Tools like exiftool do extract this data.



For the curious,
http://docs.oracle.com/javase/6/docs/api/javax/imageio/metadata/doc-files/jpeg_metadata.html#color
has some interesting information on how java determines colour profiles of jpeg
images.

Maybe the image is wrong. Wikipedia says Google chrome supports icc v2 profiles
on all platforms since version 22, firefox since version 3.5. and IE doesn't do
it correctly at all. So if its only looking correct on incorrect software
perhaps the image is wrong. ( The image in question has an icc v2 profile named
"Phase One P 25 Product Flash" [1])

Note: There is a test page to see if your browser supports ICC profiles
properly at http://www.color.org/version4html.xalter
