Uh, that's not skeuomorphic. There are pictures of light bulbs, but that's because the real world thing it controls is a light bulb. There's not a digital representation of an on/off switch you flick on or off, or a rotary knob to dim, or a thermostat dial to turn. That would be skeuomorphic, the limited screenshot that may be 3.0 is not. Now whether it's good looking or not admits of differences of opinion, i like it but could see how other reasonable people might not.
