Determining ModalController display mode?

Is there a way to determine whether or not the ModalController is going to display as a full size page navigate vs. a modal? Checking to see if ‘tablet’ is in the platform list isn’t cutting the mustard for me. Some tablets are large enough to display a modal as a modal while others display it as a full screen page navigate.

This is especially problematic for tablet users of my Ionic app that, from a UX perspective, want to click on the back button of their browsers when viewing it through a web browser. If I can predict ahead of time the ModalController behavior I can appropriately choose to use Angular UI Router.
