I don't think it's subconscious. It shows up obviously in bezel thickness and radius of corners. When they release a new product the bezel is thick and the corners are very round. As they are able to reduce the bezel size, they also reduce the rounding of the corners. This has the effect of making the last generation look toy-like and the new generation look more serious. They have used this pattern for like 20 years across many product lines.
