I don't know what you're asking about. If you update your AE to version 13.2, you will have the blue interface that so many love and so many hate. You will then be able to customize how light or dark that interface is. In a future version, there will be even more ways to customize the interface.
Your AE is not up to date.
You are, in fact, two big updates behind.
You don't have either the 13.1 update or the 13.2 update. If your CC software is reporting that things are up to date, it's clearly wrong.
