So ArgyllCMS gray calibration aims to minimize grey color error and grey brightness difference rather to aim to “exactly” your desired constant gamma across all greyscale. A gamma 1.8 dsplay and gamma 2.4 display should render same sRGB image in a color managed app as long as their profiles matches each display behavior. I had explained it to you on previous message: on color managed apps (ICC aware) it does not matter actual gamma value (your raised dark grays) as long as profile records actual gamma.

Or should I put calibration black level of OLED equal to black level of IPS panel to have same black visual level to their eyes? It will help – put same black level? Or not much because how high contrast of OLED panel? Black level of this OLED is 0.0000 cd/m^2 and Dell IPS is around 0.1-0.15 cd/m^2 (not sure exact). That why I come to ask is this normal behaviors or not? Or it just profile match the display already, only nature of OLED that more contrast and show the dark area better than IPS panel? If that the case should I keep using it and accept it as normal? I need to go and see it myself some other day. Once I go to my friend I’ve post it here. He tend to believe on Dell IPS one than OLED.Īgain, I not see it myself compare yet. When He use this OLED display with his photo edit on Photoshop he told me that their Dell IPS on black area look more black, less detail but compare to this OLED after done calibrate/profile it on the dark area more light and more detail than Dell one. OK, I not see it myself but it my friend which I calibrate his Dell IPS display before.
DISPLAYCAL CANNOT CALIBRATE WINDOWS
Windows desktop is not color managed and a lot of video players are not color managed hence there is no futher conversion to target gamma for non color managed apps. I search from google and I use RGB OLED family (sony, samsung, lenovo) correction with Xrite i1display pro. It OLED panel made by Samsung (ATNA56YX03-0), AM-OLED. Both: single curve + matrix, XYZ LUT + matrix. I just do the same with IPS panel except I enable white level drift compensation. Ok I’ve just don’t sure if I do something wrong with setting of OLED profiling or not. Verify =/= display matches your expected behavior
Verify = ICC profile matches display behavior
