I'm exporting my document as a PDF-X3 file. However the output pdf doesn't appear to have the correct profiles assigned for the contained images. Specifically, in the PDF all my images with AdobeRGB profile look flat as if they were incorrectly assigned an sRGB profile (assigned not converted). JPEG images with sRGB profiles look fine in the output PDF-X3. Embed profiles is ticked.
I'm using the trial which is 1.7.2. Color format is CMYK/8 and profile is the Blurb ICC profile.
