Banner reads "Office 365" instead of "Sharepoint". Am I in the wrong spot?

Ladies and Gents,

I registered and paid for the SharePoint Online $5.00/Mo plan. Started reading the book and noticed the top banner in all the samples/illustrations on the book read "SharePoint" but the top banner in my new site reads "Office 365". Why is that?

Am I in the wrong spot? How can I get the top banner to read "SharePoint" like the illustrations in the book?

I am learning SharePoint and that wrong banner its annoying me, makes me feel I am learning the wrong material or I am in the wrong spot. I have attached an image of my situation.

Your input and clarification will be highly appreciated. Thanks. DH.
