A few comments from another forum, based on ongoing Calman issues, and will they be fixed in the next release, after over a year of not being fixed...
"I was inspired to finally try SDR calibrating my 2019 LG 77C9 with Calman for LG after manually calibrating my bedroom 2014 LG 55EC9300 a couple weeks ago with HCFR.
With that said, the results weren't as good as I hoped for. Color Checker dE averaged 3.2 and dE max was 6.3. I assumed Calman would have no issues reigning in the Color Checker dE average to <1.5 and that my dE max would be <4.
I figured it must have just been a bad run so I ran another calibration, but received nearly identical results. I then moved my 55EC9300 next to my 77C9 and perceptually evaluated. I next carried my 55EC9300 over to my Sony BVM-D32E1W to confirm they looked similar and they do (aside from gamma). Both other displays were calibrated with the same colorimeter.
Also, I'm noticing some weird blockiness in low-luminance skin tone colors after running a 9^3 3D LUT. The colors are more accurate now, but I didn't see this when previously using the Lightning LUT.
It appears like red blocks and is easier to see in low-bitrate content but I also can see it in SDR 1080p Blu-rays. I calibrated Expert Dark to D65 and Expert Bright to .305/.322 and am seeing it with both white points (but slightly more pronounced with D65).
Does anyone know what would cause this and if there is a fix?"To which the response was...
"Sign up for the beta"Which generated the following thoughts...
"I bought Calman Home for LG about a year ago.
Had really fun at the beginning trying out all the features. But when I realized that all Autocal was providing was banding and posterization I asked for a refund. Did I receive one? Of course not!
So now I year later I'm sitting here with Calman Home for LG, still providing lackluster results and if I'm lucky(?) I might be able to get a working product before my 1 year support agreement expires in the end of April.
Doesn't seem like a fair business model in my opinion?"And...
"Been away for a while...however seems nothing is changed.
For me and for my shark fins they offered full refund but I thought they could fix it at someday.
My 1 year license period is over and waste my moneys.
Luckily there is working alternative 
"
As well as...
"Been in the same situation as you both, same issues, same outcome. I've since then moved to another calibration software, but my licence is still valid so I'm willing to give the new beta version a try to see if the long known issues have been resolved."Which then ended-up with this post from one of the authors above...
"I'm considering switching to ColourSpace CMS from other tools. Is there a step-by-step walkthrough for calibrating an LG C9 OLED so I can see what the software is like to work with?"To which the response was...
"Depending on what software you're coming from, you might be used to some kind of "automated" process. ColourSpace does not have that kind of functionality. This is intentional and a welcome change. But it does take some getting used to at first. The process for calibrating an LG OLED is fairly straight forward (so long as you don't forget any steps like SOME people around here
LOL). Typically you won't be touching the 1D LUT at all and instead will focus on creating a 3D LUT. The end result is a beautifully calibrated panel. I'm definitely not the person to be discussing the process itself. There are many experts in this thread that may offer assistance with that. This is a REALLY amazing group of people. The effort to learn this software (which is EXCELLENT and keeps improving with every release) is well worth it.
NOTE: I started with another product that claimed to "automate" the process and was not satisfied with the results. Ended up here with ColourSpace and have never looked back".
And that gained this comment from another ColourSpace user...
"+1
also coming from autocal sh.t (deactivated, uninstalled, deleted - I will never install it again for all those resets, unplugs, non repeatable and not acceptable results - my CX deserves better treatment...). ColourSpace is masterpiece, believe me, although I am home amateur compared to lot of great guys here."And this comment from another Calman user...
"Is HTL the correct licence to calibrate an LG CX using 3D LUT? I have been using PGenerator along with Calman Home for LG and an iD3 Pro Plus to calibrate manually but not getting good results even though graphs looks good."For each "another/alternative" comment, read ColourSpace.
