We'd need to see an all black image in a pitch black room to guage back light uniformity. This was a big problem on some Asus VG278HE.
For color accuracy we'd need to hear from someone who's done a calibration with the proper tools.
For lightboost performance we'd need someone to...
Would you say the xl2720t has better color accuracy and back light uniformity than the Asus VG27HE? What about the VG27H?
Which has the best lightboost 2D performance?
