DisplayCAL does not suport EDRs, read ArgyllCMS doc. CCSS is EDR in text.
There’s a EDR2CCSS tool built in ArgyII, right?
in DisplayCal, Tools tab, Correction, import colorimeter correction. I’ve been using that to import the mentioned EDRs. That’s not the right way to do it?DisplayCAL does not suport EDRs, read ArgyllCMS doc. CCSS is EDR in text.
Update, I think CS2400S uses RG_Phosphor because I got HCFR to somwhat agree with CN7.
In the colorimeter setting tab (image attached), I choose Display type as RG Phosphor (not specified), which is the supposed RG Phosphor EDR from Stuart converted to CCSS by Argyll. The readings of primaries seems to align with CN7, while although white point is still off a bit. 0.17 deltaE at x=0.3127 y=0.3291 measured in CN7 versus deltaE 0.4 at x=0.3134 y=0.3296. Meanwhile DisplayCal is still acting like a weird child.
I’m happy with the result at this point tbh, I just want to get to the bottom of it out of curiosity why DisplayCal is behaving that way.

No, apps agree because they are measurng with the same good/wrong correction. It says nothing about actual display backlight or if the correction is the right correction,
Visual whiteness may imply that it is right but withput an spectyrophotometer, it looks like it’s a WLED PFS as all its siblings.In the colorimeter setting tab (image attached), I choose Display type as RG Phosphor (not specified), which is the supposed RG Phosphor EDR from Stuart converted to CCSS by Argyll.

This means no error at all.

Don’t think I can afford to even rent a CR-250 or other spectro of the same level because the people who have that kind of equipment are pretty rare in my country. And what can I do to tell which kind of backlight tech it is or will the software just sort itself out?

Also, here’s my train of thought, based on my limited knowledge of how these apps, and how EDRs work, hope that makes sense and please correct me if I’m wrong.
– As you said, the apps agree because they are using the same correction file, disregarding whether that file is good or bad.
– CN7 has an internal backlight tech mapping for the monitor and will choose the respective EDR file depending on the tech of the monitor it’s running on, in this case, CS2400S model.
– Since after testing, HCFR and CN7 agree on readings while using this EDR made for RG Phosphor, combining with white is visually white-ish. I would conclude that it is the tech being used in the CS2400S.– Since after testing, HCFR and CN7 agree on readings while using this EDR made for RG Phosphor, combining with white is visually white-ish.

Stuart’s EDRs are not RG_phosphor… it’s just a name, called RG phosphor to be placed in place of Xrites’ default RG_phosphor EDR (whic stores spectral sample of Dell U2413 GB-LED).
RG_phosphor file from Stuart is actually a WLED PFS, as all of these non QLED modern LED widegamut displays. Plot it (specplot.exe or displaycal “i” button)
