MB Pro LED-backlighted Display: Yellowish or Not Yellowish

Last week, we published a news about the new LED backlighted display found in MacBook Pro 15". We reported such displays were delivering a yellowish rendering which could not be compensated by different calibration. Following remarks and comments, we initially decided to remove the news in order to collect additional information. Today, we will provide a more in-depth analysis of this "issue", let's first start with part of the original report:

After trying different ICC profiles settings, we could improve the overall rendering, but we could not match the quality of non LED backlighted 15" display of previous MB Pro models.
This was confirmed on 2 MB Pro 2.2GHz and 1 MB Pro 2.4GHz.
To quickly test it, use the default Apple blue desktop image, or the one featuring little stones.
P.S : the display we have used for calibrating our display is a LaCie 321.

Hereafter is the comment from Nikita Erphene, a professional photographer.

I bought yesterday a MacBook Pro 2.2GHZ, and I noticed that the display provide a real yellowish rendering
I performed a calibration this morning, but nevertheless, the yellowish tendency remains.
How can I use it for editing photo, as they simply appear yellow, even after calibrating the display!

On our request, Nikita sent us additional information:

Yesterday, I tried to recalibrate without much success. This morning I performed a new calibration using a Monaco probe, but the yellowish rendering remains. Even when applying different color temperature with the same profile, it arrived with a standard white balance and a gamma of 2.2. When using color temperature set to 6500, it remains very "hot"!.
I shoot and edit photo, and when I have many white-colored parts, it renders them yellowish!

Hereafter is one of them.

We now have a MacBook Pro 2.4GHz in our hands, and we used this photo to test the display. Unlike his report, with our unit, the photo does not appear yellowish or pinkish, without calibrating, it is almost identical to the rendering obtained from an Apple Cinema Display.
However, this test allowed us to confirmed that modifying the view angle, horizontally or vertically, as little as moving your head 10 cm (left-right or up-down) is enough to immediately see all colors getting a yellowish rendering; despite the fact the LCD display exhibit an amazing viewable range.
I might be too early to conclude with all reports we have received and based on our own experience, but it seems quite clear that editing photo with this notebook will require being perfectly in front of its display, and ensuring the view angle is optimal. To provide a comparison with previous non-backlighted models, moving away from the optimal view position, the display was getting darker, here it is getting yellow. We are waiting for additional reports before concluding that Apple has more than one LED-backlighted LCD supplier.
If the problem we report in this news will be an issue for photo and video pro users, this notebook will please any other consumers.
