    ICC_Profile first = (ICC_Profile) profiles.get(0);
    byte[] firstData = first.getData();
    for (int i = 1; i < profiles.size(); i++) {
        ICC_Profile icc = (ICC_Profile) profiles.get(i);
        byte[] data = icc.getData();
        assertEquals("Embedded ICC Profiles are not the same size!", firstData.length, data.length);
        for (int j = 0; j < firstData.length; j++) {
