Hi guys
Here are my result using DispcalGUI + Agryll + i1Display Pro following Pictus guide as always

. Monitor has been on 3 hours with the i1Display connected (the calibration tool needs to warm up as well).
Congratulations for the new monitor, the calibration result probably is very good, but
Argyll+dispcalGUI can not calibrate this monitor internal LUT(14 bits?) you need the
Dell utility that will reprogram the internal LUT to meet the desired results with the most linearity as possible and maybe in this new model the uniformity compensation can work with the calibration.
I do not know if still the case, but sadly the
Dell utility does not take enough measurements to create a "100% perfect" profile, so after using the Dell utility you can use
Argyll+dispcalGUI to have the ultimate result...
Maybe just the
Dell utility is enough, I do not know you have to test and the
Argyll+dispcalGUI tutorial got an update. The dispcalGUI Measurement Report creates a good HTML report you can send to a a place like
