The other thing the NOID looks like to me is Souvenir de la Malmaison. Did you have that one?
The OGR's in my garden always have more black spot than the modern roses, and this year the OGR's are showing traces of powdery mildew and rust, which they've never shown before. We've had peculiar weather all year here, though: June in January, and January in June. People assume the hybridizers of modern roses were just going for good colors and good bloom shape, but they were also working on resistance to disease.
The very worst offenders in my garden every single year when it comes to black spot, however, are the Buck roses, which are supposed to be so disease-free. Humph!
