I use Displaycal 3.8.9.3 with x-rite i1display pro plus. Why mode change to refresh(generic) when choose correction spectral LCD PFS Phosphor WLED IPS, 98% Adobe RGB/96% P3 (HP DreamColor Z24x G2)? When I change to LCD(generic) then correction spectral change to NONE.
It’s normal behavior?
FYI: I just try to use wrong correction for my display to see how it behave, normally I choose WLED for my Dell U2417H.

Because text file CCSS says refresh. Change text file or leave it as refresh.
PS: most extreme error should come from choosing CCFL. Maybe. Actual error depends on where colorimeter firmware data drifts from std observer and actrial spectral distribution in CCSS.
If as a though experiment we imagine a perfect colorimeter whose spectral sensivity data (stored in formware) matches some std observer, CCSS selection will not make any difference.Because text file CCSS says refresh. Change text file or leave it as refresh.
Thank you. So it intend use with refresh then.

With the correct one is WLED in compare with other 6-spectrals : 1) PFS phosphor family, 2) PFS phosphor 94% P3, 3) PFS phosphor 98%, 4) PFS phosphor 99%, 5) none, 6) CCFLL family.
Result is quite similar in each spectral not big difference, only little difference in dE/dE max, but tmore difference on gray balance-calibration only check-box dC, da+db. The correct spectral WLED give less on gray balance-calibration only check-box dC, da+db. But not much. So for me, from what you say, my i1display pro plus firmware data drifts from std observer is less or good tune I guess. It seem like little difference from choose wrong prectral-CCSS will effect result of display base on this experiment.
I’ve attach file with difference spectral from same display. Most with default option LUT 175 testchart, fast calibrate all for fast test purpose. Attach files start wit 1_, 2_. … 7_ .
This panel test is quite old I’ve to “auto” black point correction to get good gray balance as attach files start wit a1_, b1_.
I’ve also experiment all display with fast medium slow calibration, since I’ve ask before but still not quite understand optimal option to choose. I seem that medium speed calibration often give me better result base on verification compare to slow speed calibration. Attach file start with a_,b_,c_,d_ .

Main error will be located on white point (whcih is a grey, the brightest one). This should be your only test in CCSS comparisons.
