This can be improved in the stitching software. The fact that you already know the position of every camera is a big advantage, so you can take shortcuts in the stitching. Right now the stitch is probably just a spherical projection with static image boundaries, based on the known camera angles. I see a bit of individual HDR effects to compensate for the small sensor's quality, but no blending or exposure correlation between the photos.
