You could view your manifest file in code:

What you have changed is the Package Display Name in VisualElements, which is how your app name is displayed on user's device. See the Attributes in Visual Elements:

A friendly name for the app that can be displayed to users. This string is localizable;

While the DisplayName in Properties is the name of your app that you reserve in the Store, for apps which are uploaded to the Store.
