Add a notification for having out of office automatic replies turned on
When you start Outlook, if Out of Office messages are enabled, you should see a notification. Is this not what you’re looking for?

A colored bar like in Outlook for Windows would be great

My Outlook is always running. I would prefer some kind of notification in a running Outlook when OoO is turned on. I remember this was the case in Outlook on Windows.
