They will look inconspicuous, other than being a large protruding square black hump on the back of the phone. Nobody will know what they are.
It seems odd that it would be mentioned if there is a camera bump. Who looks at the back of there phone and says 'ah the slightly blue camera lens really stands out 😡
It might mean there is no camera bump for the 3rd camera so it mostly blends into the back of a black iPhone? Unlikely, but possible.
