If you look almost all things that are locked behind Amiibo you will see that those thing are really just small additional features to the full games.
Ganondorf Amiibo for TP HD is good example, 4x time never before did not exist in any Zelda game, WW HD dont have Amiibo and we have just regular Hero mode with 2x damage, so Ganondorf Amiibo basically bringing something new to the game and that feature wouldn't exist without Amiibo.
