Here is my setup:
X-Rite CMUNDIS ColorMunki Display Calibrator
30" IPS LED Backlit LCD Panel WQXGA 2560x1600 hooked up via HDMI
15" Retina Macbook Pro
I first calibrated the retina macbook pro monitor, and it was pretty much on the money out of the box, little to no difference. I then used the X-rite to match the color profile of the macbook pro monitor. Everything is sorta okay, except the whites seem a little reddish. This is especially apparent if you take a picture of the screens side by side. The LCD is brand-new, not sure if that makes a difference.
To the naked eye however...
To my eye AND when you take a picture of just the 30" display in question up close without any other screens in the shot it looks like the white is normal. However most colors seem super neon-like on the 30" display. The frustrating thing is that using a digital color meter the colors are being resolved correctly, but the colors are rendered on the screen are not.

I know it does not look this way perhaps when captured on a camera, but when actually looking at the screen with my eyeballs everything labeled "WRONG" is far too neon colored. Everything labeled "CORRECT" looks the same across both screens AND is the correct color I am supposed to be seeing.

Side by Side with Retina Macbook pro (calibrated) and iMac (uncalibrated)
My question is: given the symptoms, where would I start to match up the colors between the two screens?
