After some investigation, I have yet to find a way to retrieve the individual MCU blocks using MediaUtil's API. You can certainly retrieve the number of MCU blocks, and even specify to read the full image incrementally; however, it looks like the only way to retrieve actual pixels is by requesting the full image.
