What I do for Krita, and what's as far as I know is also done in Gimp and a 
couple of image viewers is something like this (where KisProfile is a wrapper 
around an lcms profile that can be initialized with just the bytes):

KisProfile *  KisProfile::getScreenProfile (int screen)
{

#ifdef Q_WS_X11

    Atom type;
    int format;
    unsigned long nitems;
    unsigned long bytes_after;
    Q_UINT8 * str;

    static Atom icc_atom = XInternAtom( qt_xdisplay(), "_ICC_PROFILE", 
False );

    if  ( XGetWindowProperty ( qt_xdisplay(),
                    qt_xrootwin( screen ),
                    icc_atom,
                    0,
                    INT_MAX,
                    False,
                    XA_CARDINAL,
                    &type,
                    &format,
                    &nitems,
                    &bytes_after,
                    (unsigned char **) &str)
                ) {

        QByteArray bytes (nitems);
        bytes.assign((char*)str, (Q_UINT32)nitems);

        return new KisProfile(bytes);
    } else {
        return NULL;
    }
#else
    return NULL;

#endif
}

That's as standard as it comes and it should be in the create spec, together 
with the default locations of icc profiles. What is missing is having a 
control panel to set the property.
