Received my stock i1Display Pro. The software that comes bundled can't do hardware calibration with the UP2414Q, and it only created an ICC profile although I had IDC and wide gamut enabled.
I used Dell's own version of i1Display, which comes with the monitor, or can be downloaded from Dell's website. With that you get ADC, which does hardware calibration. It also enables uniformity calibration, with a 3x3 or 5x5 grid. This is to mitigate any color shifts in different sections of the display.
ICC profile with the bundled software takes around five minutes. I hardware calibrated the monitor, and it took a good 20+ minutes despite the very fast puck, as it did two full passes, and some additional testing along with the uniformity calibration. You can save different calibrations as presets (eg. ARGB and sRGB) if necessary. Didn't play around with the options, yet; I just used 120cd brightness (equaled to roughly 22/100 Brightness in OSD) in ARGB, and the results look great.
