Could it possibly be that you're brightness level on the 2011 isn't up all the way?
Sorry to say, but if that is so, your eyes will adjust.
This is really frustrating because I bought the glossy for entertainment purposes because I assumed it had more vibrant colors and was brighter. It is definitely more colorful and the colors seem to pop out more along with a sharper picture but the brightness looks identical to my antiglare. I was hoping for deeper blacks and I don't notice them even at the maximum brightness level settings.
