    Color mapping to normals direction

    x-, y-, and z- components are mapped from [-1 1] to [0 255], even though z cannot be negative. So yes it means that you will never use the range between 0-128 for the z-component. You can always compute z-component by z = square_root(1 - x*x + y*y) after you map the x and y components between [-1 1].
