What's your point? You said you haven't seen anything better than a 'Shiny Xbox Game' on the 360, I gave you one to try. I'm not going to try to argue that 360 games can/will look better than PS3 games on an appropriate display device.
Edit: To add to that last point, I don't think we'll be seeing any clear differences in graphical quality between the 2 systems for a while.
I came across this link yesterday that showed Ridge Racer 7 (PS3) vs Ridge Racer 6 (360), both launch games for the respective system, and it would be pretty difficult to know which was which just by looking at them. I guessed that the top one was PS3 since the car was a little smaller, which could be due to the higher rez, but it could have just been a different camera angle.
The PS3, by the numbers, has a higher potential for better graphics, but we may have to wait until MGS4 comes to say definitively "there's no way the 360 could do that".
