Followup: It seems Firefox is indeed able to use the matrix part of XYZ LUT with (swapped or not) matrix profiles created with Argyll CMS (just tested, FF 3.6.3, Win7). I think in the case of the profile not being used, it can be related to this bug, atleast under Windows (heh, I opened that myself about two months ago, must've forgot about it):


ICC display profile is not used under Windows if its filename contains Unicode characters

Hi,

The Windows 7 "Photo Viewer" application uses only the matrix part and
shows RGB shifted to GRB, while the Windows 7 file manager
("Explorer") uses the LUT part to colour manage its JPEG previews, so
those are shown with correct colours, as do other applications that
invoke/use the Windows CMM.

The Windows 7 explorer thumbnails definitely aren't using the display's
associated profile. My guess is that they are colormanaged, but probably
with a default internal destination profile (sRGB? On my wide-gamut TFT
the thumbnails look overly saturated). Maybe Firefox is doing something
similar, ie. silently defaulting to sRGB as destination profile if it
can't cope with the display profile?
