EDIT: Yes, the jpeg seems to be cropped
I think its the distortion correction that pushes those corners out. It really has monsterous distortion. Otherwise they wouldnt keep the data in the file. I wonder though if the sensor is bigger than ff or if you effectively get a smaller than ff sensor.
The dpreview galleries have unusable samples to check distortion but the older q2 galleries have if I remember correctly. And the lens should be the same.
Edit: I see in your sample that the mid frame window is cropped as well... so perhaps not just distortion correction.
