Yeah it looks like the default icon. If you want it like that, I think you just have to make sure the email account isn't linked to other any other inboxes you might have.
Or if you are referring to the background image, then you will also need Windows Phone 8.1
I dont know,my email tile looks like the one in the picture that says "google mail 2" except theres more then 1 little envelope since i have different emails :/
