400cc, Mentor & breast changed shape, is it obvious to other surgeons? (Photos)

I had breast implants September 2021, 400cc mentor silicone dual plane placement. My left breast (right in the picture) was looking good at 6 months post op, but when I reached 9 months it looked less full, like it hadn’t dropped fully again. My surgeon says it’s fine and not capsular contraction. I just wanted to ask if the change I’ve noticed are obvious to other surgeons and what it could be? It doesn’t hurt but feels like firmer than the other one.
