You can try to edit the 'id' entry of 'ISO Coated v2 (ECI)' in

?/texmf-context/colors/icc/context/colorprofiles.xml
(just replace 'FOGRA39' with 'Fogra 39')

...
    <profile>
        <filename>ISOcoated_v2_eci.icc</filename>
        <colorspace>CMYK</colorspace>
        <class>prtr</class>
        <id>Fogra 39</id>
        <info>ISO Coated v2 (ECI)</info>
        <checksum>bda07efcacf5377e91edacb0454ea7e5</checksum>
        <version>2400000</version>
        <url>http://www.color.org</url>
        <outputcondition>Offset printing, according to ISO
12647-2:2004/Amd 1, OFCOM, paper type 1 or 2 = coated art, 115 g/m2,
tone value increase curves A (CMY) and B (K)</outputcondition>
    </profile>

...

If I remember it right, this 'id' entry is no unique identifier, as some
profiles use the same value here. But I have to refresh my knowledge
about icc profiles a bit, before I can give a final answer.
