Reviewed.com has some really great scientific data and analysis on their television reviews, including measuring color temperature accuracy by detecting and comparing the light output of each sub-pixel (green, red, blue). The majority of TVs they test actually have substantially more blue luminance than the other two colors, making them too cool. That's often intentional, because cooler pictures look subjectively "brighter" and stand out more on showroom floors.
