Merely having balanced inputs/outputs is indeed different from having a balanced circuit design (input and output).
Just because a component has balanced inputs/outputs does not necessarily mean that its circuit has been designed that way.
If properly implemented, a balanced circuit design will lead to, among other things, a lower noise floor due to what is called common mode rejection.
