MRI results - capsular contracture or muscle placement issue? (photo)

I had breast implants placed under the muscle. Early in the healing process the right implant was higher than the left, but my surgeon did not seem concerned. One year later I had an MRI as the asymmetry was still there and I wanted to check for rupture. No rupture, but do these images suggest capsular contracture or some sort of surgical error with the right breast? Including the left breast image as well for comparison. My surgeon says the pectoral muscle is holding onto the implant and suggested that it won’t resolve without surgery.
