As far as I can see the detection, if a cmyk image is contains only gray
values, is wrong: if cyan, magenta and yellow have the same value it's not true
that we get a pure gray value, they must be 0! And if we do it in that way,
we'll get problems with overprint. Therefore it should be:

if (numComps == 4) {
  int compCyan;
  isGray = gTrue;
  while ((compCyan = str0->getChar()) != EOF) {
    if (compCyan != 0 && str0->getChar() != 0 ||
        str0->getChar() != 0) {
      isGray = gFalse;
      break;
    }
    str0->getChar();
  }
: : :

But probably we never will run in a situation where a CMYK image will contain
only values where C = M = Y
