The banner's colour is based on the "Incident Status;" it's green because services are currently operational. It would be yellow or red if the impact were more severe.
Using only color to communicate the status is confusing. If you want to communicate something, it's often best to just say it. The color can be a visual reinforcement of that. Then your explanation would not be needed.
But that's not were the confusion is created. I don't even see the status field on mobile without scrolling. You don't have a missing status field, you have too much confusion, because the field and/or the color have a placement mismatch.
