I assume the extra padding was a function of touch screens becoming more prevalent since trying to hit the 2003 style buttons with a finger was not that easy, although I don't remember offhand when touch first started becoming a thing in Windows so it might have happened the other way around. But either way it's likely still a factor in why the ribbon with its extra padding has stuck around.
Tablet and phone touch devices also don’t have keyboard hotkeys like desktops do. In a desktop computer you can afford for the icon bar to be a tiny cramped piece of shit because it’s really more of an early crutch until you learn the hotkeys you need. That mechanic doesn’t exist on a phone or pad. You need the menus and buttons to actually be usable permanently.

I think it’s a function of greater screen resolutions being available.
