I've tried 3 times to make a good blueberry beer, once using blueberry extract (very artificial tasting), once with juice(not much blueberry flavor but probably the best I made), and once with real blueberries (purple in color, not enough blueberry flavor to notice) and then gave up. I think if you get a good quality blueberry extract you might like it but the extract I got wasn't that good. I've quit trying to make one. Seadog Blueberry Wheat was pretty good but I don't know just how they get their flavor. I've sampled one at a brewpub that was made on premises but that one wasn't much better than any I had brewed either.
