I don't really understand why Adobe RGB in 4K display is so bad. I remember Precision 5510/XPS 15 9550/9560 have very good result
It's probably because they forgot to disable the default display calibration in the intel graphics control panel. The calibration restricts the colour space to sRGB. I had my XPS 15 9570 with 4k panel show nearly identical results until i disabled the option. After that, DisplayCAL + Xrite i1 Display pro showed 100% Adobe RGB coverage. This was my experience with the 9570 at least. Lets see if they retest it with the option disabled.
