You need to set the ApplicationViewBoundsMode to UseCoreWindow:

 ApplicationView.GetForCurrentView().SetDesiredBoundsMode(ApplicationViewBoundsMode.UseCoreWindow);

The default is ApplicationViewBoundsMode.UseVisible which is your current behavior. With ApplicationViewBoundsMode.UseCoreWindow, the command bar, status bar nor the software buttons will occupy space.

If you need to change your margins or anything else when the BoundsMode changes, register for the VisibleBoundsChanged event:

ApplicationView.GetForCurrentView().VisibleBoundsChanged += OnVisibleBoundsChanged

You can read more in the official documentation.
