Can you search for the *.cube file that you are using (“Resolve 2019-05-19 10-02 0.3127x 0.329y S XYZLUT+MTX.Rec709.B0.0,2.4Gawn65.cube”) in “C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT” and attach that? There has to be a difference between that file and the original.
The archive you attached was the 115 patch version, but that shouldn’t matter. If that wasn’t the one you had problems with, please attach that instead. Probably misread(s) due to (too low) pattern delay would be my guess.
That one seems to have a dynamic contrast feature, make sure it is disabled. Also make sure macOS night shift doesn’t kick in during measurements. Other than that, pattern delay of 1100ms seems to work fine in your case, that was the delay you used for the smaller profile. Maybe bump it up another 100ms just to be safe.
I would also recommend profiling the monitor in its native gamut mode.
