Hi fellow color enthusiasts.
Just wanted to share something I seem to have discovered in Argyll’s collink regarding the viewing conditions. Maybe this will help you create better LUTs too.
I have a relatively low white luminance (around 104 cd2) and watch my display generally in complete darkness or low light. I’ve tried various settings afforded by collink, but nothing was especially good until I started to play with the viewing conditions. So now I use the following argument: -d a:(your blackpoint luminance):b:0:l:(your whitepoint luminance). The white luminance is specified in your display profile, which you can view with ICC Profile Inspector. To get the black luminance I enable color management in mpv, then get it to output to a log file. You can find the calculated black luminance then in the log file. This seems to greatly help with the contrast, especially coupled with the perceptual intent. Regarding the source profile, I use the standard 1998 HP sRGB for images and the adobe 2.2 gamma rec709 one for movies and videos (this seems to work best). The resulting cube LUT is then loaded into DWMLUTGUI, and there you go. This argument can also be added in DisplayCal via the menu option, which will then be used by the 3DLUTMaker tool.
Hope this helps!
Forgot to mention another thing. Maybe it’s placebo, but applying the monitor profile’s cal file also helps (the -a key), even if it’s just a straight line effectively.

This should be stored in icc profile unles you choose BPC in profiling stage (as most people do). Also you can get ot from “report on calibrated/uncalibrated device” or using “dispcal -r” on argyllcms commandline

What is your current OS?
DMWLUT seems broken on w11 24h2/25h2 no matter which version I use. I will be very interested if it is possible to run it in current W11 25H2, it was a great software in W10.To get the black luminance I enable color management in mpv, then get it to output to a log file.

Yes, looks like you can also get the blackpoint luminance from the Y value in the bkpt tag when viewing your display’s profile in ICC Inspector. I realize using the mpv log is an exotic way to achieve this, I just couldn’t get “dispcal -r” to work somehow. Thanks for the suggestions!

I will be very interested if it is possible to run it in current W11 25H2, it was a great software in W10.I have Win10 21H2, which is also rather whimsical regarding which DWMLUT versions it can run, some won’t load the lut, some won’t run at all. I managed to compile the latest version using Visual Studio, and this has been working nicely so far. I know it’s a long shot, and a bother to install all those packages, but maybe this might just be the solution for you.
An alternative option, albeit a limited one, would be to use reshade. At least it can be made to work in most videogames and video players.
