@ConnecTEDDD , does this new probe matching capability improve meter profiling with c6 and i1pro2 as spectro?

The problem with i1PRO2, for that method is that it will require to read some patches with low luminance and it may have problem to provide an accurate reading.

So if you use an inaccurate reading, this will provide later worse results.

Ideally you have to take volumetric measurements with each meter, this means you need 5-Point Cube measurements.

When you take 5-Point measurements means than you will measure with 4-Point of Luminance (25%, 50%, 75%, 100%)

Steve recommends to use a high-end spectro as you will measure patches not so bright.

For example, if you measure an OLED with 100 nits peak and native gamma 2.2:

The luminance levels of the Red patches will be:

100%: ~21 nits
75%: ~11 nits
50%: ~4,5 nits
25%: ~1 nit

The luminance levels of the Blue patches will be:

100%: ~7 nits
75%: ~4 nits
50%: ~1,6 nits
25%: ~0.4 nit

So using a better spectro, you will have better results.

But with i1PRO, I think you can try for the start the small cube, the 3-Point Cube.

Or export the 5-Point Cube patch to CVS file, open with excel and remove the lowest points (the 25%)....Steve can comment if this may work.

As the owner of a i1 Pro 2 myself, I will test also this:
1) take 5 point cube profile with spectro and colorimeter (in my case a basICColor Discus)
2) export low luminance readings from the discus profile and correct them with FCCM (I have an excel spreadsheet to do that)
3) substitute critical low luminance readings into the spectro profile with those FCCM corrected at point 2)
That would solve the low budget spectro problem that this new feature could bring.

Question: if we want to verify our calibration, do we have to profile again probes after the TV is calibrated? A profile is not a Matrix so it will not “self-adapt” to the new TV state, right?

Seems like adding points back that you know would have errors due to FCCM vs WRGB OLED issues would likely be worse than having no points at all.
In my mind it seems that if you just don't have those suspicious points then the LUT interpolation to the closest workable values would give better results than FCCM.

We (a user!) found a bug that had crept in, totally unrelated to the new Volumetric probe matching development.
Probe setting were not being saved!
Fixed version already uploaded.

Until we won’t test all, we won’t know what’s better.

Steve, please check the download package or link that's being sent. I got 2987 again, and the download link is exactly the same as I received yesterday.

That did it. What was strange about what I was seeing before was that the Changes pdf file reflected those changes for 2988 - I opened it - yet the installation folder was for 2987, and that's what it installed. Everything matches now.

Anyone figured out an .csv file cube yet for volumetric profiling without 25% lum and down (to be used for i1pro2/klein k-10) i cant figure out how to do it myself : )

What cube file you have generated?

For example, do you want to remove the 25% from the a 5-Point Cube patchset?

The ‘Volumetric Probe Matching ‘ info has been updated to the various LightSpace website pages.

For Volumetric Probe Matching a profile will need to be cube based, or valid Quick Profile such as Primary Only, or Edge. (Volumetric Probe Matching will always work best with uniform profiles, not random ones)

Best results will be attained when the display peak white is set to be close to the target peak white. (Say, 100 nits for SDR calibration)

The Black Level of the display should also be raised to a level that both probes can read black consistently, without error. (Most probes can read around 1 nit accurately)

Profile the display with each probe in-turn as normal, with 'None' selected within the 'Active Probe/Display Data' options. (You should use a None/Bypass/Default pre-set within the Tristimulus, not a display specific matrix pre-set)

The profiles can be 'Characterisation' cube based profiles, or 'Quick Profiles'.

After profiling both probes, open the 'Manage Colour Space' library, and use 'Generate BPD' to convert the profiles into Probe Matching files.

The probe matching files can now be selected within the 'Active Probe/Display Data' drop-down menus within 'Options', exactly as for 4 colour matrix probe matching.

Nevermind, at a first read of the new probe profiling feature I haven't read that it creates bdp from each profile.

Removing patches will be unlikely to work.
The Volumetric Probe Matching requires a simple 'uniform' profile to be used.
As the User Guide info says, you will do better to just slightly raise the black of the display so both probes can read black.
