Calibration does make a difference. Mine is a 9CBD screen, and I'm happy enough with it although I would prefer a 9C9F, I won't be returning this macbook pro. Problem is with colour sensitive applications, it's not going to be colour accurate. Video and photography apps will look different on the screen no matter the calibration. My 9CBD has a yellow push which gives everything a yellow tint, and affects the greens too. On the desktop you can't tell the difference but in video you can.
I have the same screen model (9CBD) and I definately have to second your observations. I really can't get this screen to display neutral colors. Otherwise the screen is rather good (bright, uniformly lit, acceptable viewing angles ).
But especially video material exhibits unnatural looking skin tones (very saturated yellow/orange) and nature scenes (fluorescent greens). Also, in-room scenes with low lighting tend to look brown/yellow-tinted and a bit grainy and washed out.
Calibration using the OSX integrated tool didn't really help the color tint/shift but at least improved visual appearance otherwise. Switching to sRGB makes video look more neutral but introduces a blue tint everywhere else. The spider2 Profile for the 9CBD posted by a user on this board is so far the best compromise to me, although colors still aren't perfect.
I think these problems basically come down to wide color gamut (WCG) screens being fed with normal RGB values and Apple not providing suitable support for WCG in OSX. First thing for apple should be to provide better factory screen profiles that accurately describe the colorspace of the particular panels mounted. Maybe also someone with an officially WCG aware colorimeter such as spyder 3 will be able to do a better calibration profile.
But even then, as I understand the whole WCG issue, there still is application / OS support needed to accurately map the RGB values of a particular source to the wide colorspace of the screen.

Aren't the 9CBD and 9C9F displays the same model/manufacturer? (LG/PHILLIPS)?
Yes, from what I gathered, terminal app reveales "LP133WX3-TLA1" for both the 9CBD and 9C9F. Hhm, would be interesting if someone compared them side by side....
