I consider this a so what data point. DS/3DS and WiiU largely barely used dual-screen but for maps or menus. Far smaller % of games made good use of the 2nd screen. Hell, even Nintendo didn't do it all that well when it explicitly tried to with games like Nintendoland.
It also frees up the computing hardware to only focus on a single display, which is very good.
