ios 7 suffers from two personalities. The first one you meet on the home screen, and for most of the icons. The over saturated, my little pony-esque, gradients. These over saturated colors ARE NOT minimalist, and instead fly IN YOUR FACE. Compared to this the color scheme of ios 6 is minimalist, as it used much more muted tones and as such is much more minimalist on the eyes then this craziness. Then you have the actual minimalist qualities, which is usually thin icons, thin fonts, and textureless boxes. This completely clashes with the non minimalist LSD drug trip that the icons are going for. You can't really call the entire thing minimalist when the icons are screaming 'LOOK AT ME!'
