Here are some quick profiles of the ASUS PA32DC.
The Precal profile maps the profile data to the native response of the display, so you can see it's relative underlying accuracy.
The profile shows approx. the same level of underlying non-linear errors as Sylvian found with the LG, requiring a 3D LUT for accurate calibration.
(A 1D LUT and 3x3 matrix will produce 'ok' results, as Sylvian also found with the LG.)
The Postcal profile targets Rec709, and shows all verification measurements to be sub 1 dE2000.(Ignore the Gamut Coverage value - I am using an unreleased Alpha, and the reported value is wrong.)
Taking a bit more time, especially with probe matching, suggests even better result will be possible.
(I did do a second run, and got an even better RGB Balance response, but there is something slightly weird happening there, which I am discussing with ASUS.)
