Currently, the only bonus information shown is ID, Name, Value, and Territory ID's, but Color is not shown. Bonus colors should be available in the API. Territory center points are also not found anywhere in the API. It would be nice to have those accessible as well.
I don't know why it is this way and I don't think it should exclude such information.
