Hard to compare, BoTW does not even have any human voices. So that means audio goes close to nothing. The textures are very low, so no need to waste much on that. My guess Surround Audio, plus the High definition Textures take a lot of space. Compare for example Diablo IV, which gives you an option to download 1/2 of the game size if you don't need high resolution textures. 45GB vs 90GB.
