New MBP Display - Color Banding in Gradients correctable?

Hello!
I just recieved my new MBP (the one with the new LED Display)
and noticed that I have color clipping and strong banding in all
dialogboxes where I can select a color (for example in PS).
I made a photo of my screen that shows the problem.
As you can see in the attached image there is clipping of red
and blue in the corners as well as a strong band in the green
color area.
Edit: The Gradient Test was carried out using LCDTest (free)
from here: http://www.versiontracker.com/dyn/moreinfo/macosx/23237
I would like to know if this type of color problems can be
fixed by profiling the monitor with a colorimeter or if it is
a hardware defect.
At the moment I'm still in the 14 days return policy so I
could still ask for a replacement from Apple.
Comments highly welcomed on this one!

Hey, there's got to be someone in this photography
forum who has the force

I'd have apple replace it. Things should just work when you get them.

Yes thats very interesting, finaly a person that has a new
mbp and a colorimeter. I wrote him a mail and will report back
what he has to say about the banding after calibration. Thanks!

I got a colorimeter (Spyder2) while I was waiting
for an exchange mbp from Apple. Today the new
mbp arrived and I made the calibration test myself.
The good news is that the line through Gradient issue
almost dissapears! And is not visible anymore in ps
color selection dialogs. I can very much live with that
The bad news is that my new mbp has a very obvious
uneven elumination on the bottom and right side
of the screen (there is an ugly hotspot just above the
mbp logo too) so I'm returning the thing for the 2nd time.

I tried the ColorEyesDisplay Pro demo
with my Spyder2 on the mbp and got
really nice results with all deltas below 0.8
and a line-free (smooth) gradient. Minimal
clipping in the red and blue highlights is
still present, but that seems to be the
limitation of the 6bit laptop display.
Does anyone other than me actualy read this?

I just found this thread, for some reason. Interesting and disappointing to hear about your troubles with the new displays. I was very hopeful that they would be a big improvement over the LCD displays, what with all of LCD's faults.
Keep us posted!

His verdict is that it's "very, very good" and the best gamut he's seen...in a laptop screen, anyway. iMac screen still blows it away, but by less than earlier laptop screens.
That sounds very good. Without
color calibration the first shiped mbp's
had a horrible default color profile. It
seems that apple has adressed the issue
with recent software updates. Apple
is using two different panels from two
different manufacturers in the new mbp
btw. Possible that this was (is?) a source
of the differences people are getting
with their displays?!

Anyone care to share battery life on the MBP LED models? I will be in good shape to order one by the end of the month, but I have no idea what to expect for bat life...

I tried the settings the article recommends
but with Luminance set to Maximum (120cd
was too dull for me):
> Gamma 2.2
> Color Temperature 6000K
> Luminance Maximum
The result is an even smoother gradient without
clipping and very accurate colors (all deltas below 0.8).
I am very happy with this now (and excitet, can u tell?)
and would trust the display to be accurate enough to
edit for printing. This is what I'm going to try out next
