The Starbucks roast means burnt, oily coffee beans (and they are usually not particularly fresh). Such beans can clog some grinders, but they do not break the burrs. However, that’s why most superautomatics don’t do well with oily beans. They prefer a lighter roast.
Oily beans are not universally ‘bad’ – or ‘good’. Beans contain oils, release those oils when roasted, and can express those oils to the surface over time post-roast. But this is complicated because the oily-ness can be factor in some hardware – especially full-auto bean-cup espresso machines.
Likewise, how can you tell if coffee beans are oily? If coffee beans are roasted to a dark roast, as well as becoming a very dark brown, the heating process makes much of the oils and oily compounds within the bean to come to the surface and give a sheen that looks greasy. Essentially, coffee beans that look oily are dark roasted and should have a dark brown color.
