Leaves are full of blackspot in this photo. How blackspot-prone is this rose?

Question: Is it really a mutation of R. rugosa alba? I just purchased R. rugosa alba-plena from Heirloom Roses. the stamens are dark in the photo . the stamens of extremely highly rated (9.1) R. rugosa alba are yellow. Does this mean rugosa alba-plena is not a mutation of rugosa alba? Both flowers in both photos have fully intact petals. Do the stamens turn dark before the petals fade?

These stamens are yellow too, like on most roses. When they turn darker, it is a sign that the pollen has already picked up. - A service of the plant for pollinators telling them to use their energy elsewhere. Stamen colour is not a characteristic sign for parentage.

One of the first roses to get powdery mildew in late September here Western Oregon. I need to apply fungicide. Very nice foliage and habit. Flowers are nicely colored and fragrant.
