So you suggest I should leave it as it is and there is no use for fine tuning? Actually I am quite satisfied with the results as every REMUX is awesome on it.

A 3DLUT for madVR could be beneficial but you don't want to adjust your white point. I haven't actually seen your gamma results but a 3DLUT is a great way to get a perfect gamma. Only looking at primary and secondary colors and the gray scale is not enough information.

The settings you showed for DisplayCal were good, except I would change the gamma to BT.1886 and the white point to as measured (or native if that is what DisplayCal calls it). Unless your gamma is already good.

Even with all those options set to "as measured" a 3DLUT can be helpful, it won't make a big difference in all scenes but can help a lot in some.

However, if you do a "Color Checker" scan in HFCR and everything is below 2 dE, maybe don't bother with a 3DLUT.

In my case, is it necessary to use the Interactive Display Adjustment option? I just want to refine my CMS because I've calibrated everything with BT1886 CALMAN software!

Can you also remind us which TV do you have, Attila?
Well, here's what you can do: select a different user preset on your TV and reset everything back to default under it, than you can create a proper 3dlut with DisplayCal and you can easily switch between presets on the TV to see the diff between CMS and 3dlut calibration.

Well, I'd rather go for 2.4 gamma if you can select it on your TV as well You can take a look here, why, Attila.

As far as modding the default MadVR preset in DisplayCal, you only have to change:
- the amount of patches on Profiling tab (I used to create around 4000)
- and the above mentioned gamma settings on 3dlut tab

And yes, you have to adjust the white point of your TV!

When it's finished, you have to make sure that the generated 3dlut is properly set in MadVR, then you can go to the verification tab, and set the chosen gamma there as well, and select XXXL video profile.
And you can also make a profile with HCFR as well, as Asmodian said.

Their white point is already within 0.2 dE! Why would they want to use software to mess with the white point at all? Any change done in software would reduce contrast for nothing.

for evening/night usage (with just a dim environment light on): 2.4 like gamma with slightly elevated shadows at the lower end of greyscale
Guess what BT.1886 is.

As far as I remember the avg. in Color Checker was around 0,9.Including the skin tone, blue sky etc.

Thanks guys!!

Well, then he doesn't have to change it then

I notice the closer I get RGB to each other the less difference I see at the end of the calibration when I click preview. Essentially just adjusting those values is what you do on a display not connected to a computer, and can use HCFR. So is there an actual reason to "calibrate" with the software and have it adjust levels if not doing pro color work? I leave the settings on "as measured" anyway.

Do you mean 3dlut?

If your white point is already as good as your example I strongly recommend you not calibrate it in software. I also recommend you NEVER calibrate the brightness with software, for any reason.

A 3DLUT can still be quite helpful, and even an ICC profile if your gamma or gray scale need work, but simply set the aspects that are already good to "as measured". The less you adjust in software the better.

Is it worth creating a 3DLUT for every color space ie Rec.709, SMPTE-C, EBU/PAL?

I don't think so. I have 2 for rec.709 (night, day), and similarly 2 for hdr->sdr conversion.
