Disease ID question

A customer and former neighbor of mine gave me these pics, wondering what is wrong with her Morden Centennial.

It really doesn't look like blackspot. Very soft yellow spots, looking just like they're blurry.

Virus?

I'd first check for any sucking insects on the undersides of the foliage. It doesn't appear to be a disease nor does it look like anything I have ever had diagnosed as viral.
