Why does it matter whether the contrast is set to None if it's not being used?

:param contrast: A value between 0 and 1, specifying the initial LCD
    contrast. Default: 0.5. Has no effect if pin_contrast is ``None``

Oh, sorry, I missed that contrast is a property, and not a plain attribute :slightly_smiling_face:
