It's called false advertising, to the general public anyway, but they all get away with it.
The buns are actually bigger, there is more filling inside, so it's not just making it look prettier, they are misrepresenting what actually goes into a burger.
It's like advertising a Toyota Hilux, but they use a Tundra in the ad, with huge inside shots and show how the tray is so big as well !
If you want a proper burger, find the local takeaway shop that does a proper one....for probably less money than Ronald !!
