That's because Heaven & Hell hardly had the name recognition Black Sabbath and Ozzy do. As great as Dio was, he never came close to the level of popularity Ozzy has. Before H&H, Dio was playing venues that fit maybe 1,000 at the most, while Ozzy has always filled arenas/amphitheaters very well by himself thoughout his career. Sabbath without Ozzy also would play much smaller venues.
The fact that they haven't toured as Black Sabbath for a number of years now and Ozzy's infinite popularity should be enough for them to fill up amphitheaters in a respectable way this summer.
