Very rarely I saw Itachi his Sharingan De-Activated ...
If that Uchiha has potential he can keep it activated ...
If that is the case, then we would see the whole uchiha clan running around with activated sharingans, now would we? But we dont. There is a reason behind de-activating a sharingan when not in used, whether it consumes amounts of chakra to keep it activated or for whatever reason. Same for kakashi and danzo keeping it covered up, could be for the same reasons/keep it away from any light when not in used.
Once again, Tobi is not an original Uchiha, it is clear he stole Obito's right eye, however it still maintained Obito's original Mangekyou design. Transplanting a sharingan into a new host will activate a new Mangekyou design ONLY if the new host is Uchiha. If the new host is not an Uchiha (kakashi), the mangekyou design will stay the same from its original host (Tobi and Kakashi).
This is proven when Madara transplanted Izuna's eyes, the new Mangekyou design was a mix of Madara's own mangekyou and his brother's. This is proven again with sasuke's mangekyou when he transplanted Itachi's eyes.
