If the two monitors in the video are calibrated, which the description says they are, then they should be displaying exactly the same colours. The pink colour cast is too obvious. There could be something wrong with the calibration because the calibrator will "remove" the pink. I've an extremely old yellowing monitor and the calibrator was able to remove the yellow old colour cast without problem so I don't see why the pink colour cast is still there.
Most of Dell's IPS panels (those that support 99% sRGB) should perform similarly. So whether you get a new or old model does not really matter much. If an old monitor is selling much cheaper than a new model, it is definitely worth consider the old monitor because the colour reproduction is probably going to be the same.
The only reason to get UP2716D is if you need to compare the screen against printed proofs (for photographers or graphic designer), or against other screens (video editing for big projects). If not, the U2717D's 99% sRGB is more than sufficient for general use, even for graphic design, photo editing.
