Mh, the file size of "ISOcoated_v2_300_eci.icc" is around 1.7MB. I highly doubt that ConTeXt can compress it into a 10KB PDF.
But I'm not so sure if PDF/X-3 needs embedding (there was an exception). Never used it (only PDF/X-4p) and I can't remember the specifications (all those stuff was added over 8 years ago).
I just assume you have installed the icc profiles properly (needs a manual installation!) :D
There are some profiles in the context installation. At least something was found: backend > profiles > profile specification 'ISOcoated_v2_300_eci.icc' loaded from '/home/juh/context/tex/texmf-context/colors/icc/context/colorprofiles.xml' backend > profiles > omitting reference to profile for intent 'ISO Coated v2 300% (ECI)' But, yes the size is too small to have the whole profile incorporated. juh
