Tilman,
Thanks that was a big help.
Here is a short Groovy Script the "before" and "after" appear to show that only
the appropriate Named Separations are modified.
String inFile = "e:/testPDFs/_VarnishDiecutCrease.pdf"
Path fileLocation = Paths.get(inFile);
List<String> SeparationList = ["VARNISH", "Crease"]
byte[] pdfHandle = Files.readAllBytes(fileLocation)
PDPage pdPage = getPDPage(pdfHandle, 0)
PDResources pdResources= getPageResources(pdPage)
COSDictionary pdResDict = pdResources.getCOSObject()
COSDictionary ColorSpace = pdResDict.getItem(COSName.COLORSPACE)
ColorSpace.keySet().forEach({
PDColor color = pdPage.getResources().getColorSpace(it).getInitialColor()
PDSeparation SeparationSpace = color.getColorSpace()
if (SeparationList.contains(SeparationSpace.getColorantName())) {
COSArray cs = SeparationSpace.getCOSObject()
cs.set(1, COSName.getPDFName("XXXX"))
}
} )

AFAIK the name isn't used, so you could do something like
sepCS.getCOSObject().set(1, COSName.getPDFName("TANZONE 12345 ABC"));
