From what I've seen on my mid-2009 MacBook, and the late-2009 MacBook's price being the same, I'd say that the display wouldn't be all that great but would be better than those inexpensive Windows machines.
My MacBook doesn't look better than my 2004 PowerBook when I'm editing photos but if I look at a different angle, the MacBook looks worse. Of course, replacing a panel in 2004 was almost equal to the price of the computer.
