Thank you both for taking the time to respond.
For the time being, even a 3D LUT for SDR is giving me headaches, I don't even dare think about HDR
My first attempt at generating something for SDR failed miserably... I went wild with the WB 2-point adjustments and ended up with a terrible picture. Oh well, at least this way I learned that one shouldn't increase the red gain, nor muck about with the cuttoffs for any channel.
Half a day later (after reading some 1000 posts from this thread) I gave it another try. Looks somewhat better but I'm still not happy with:
1) how it elevates near-blacks - Yes, I was hoping the 3D LUT would help with the minor black crush on the set, but dunno... maybe I'm not used to this but it looks off to me in mostly dark scenes.
2) a slight greenish tint to skin tones - At the initial whitepoint check, I had to set the main green gain to -1, main blue gain to -2, 100IRE green gain to -2, 100IRE blue gan to +2 so as to give me as little of a DeltaE value as possible to start with.
Now, my feeling is the 3D LUT somehow overcompensates for these negative gains to green and overshoots the results. Just a guess as I have no experience whatsoever.
Also, the profile self check DeltaE*76 average sounds wrong to me: average 0.52, max 5.09, RMS 0.65?
(I'm basing this on the general consensus from reviewers that the Panasonics are closest to reference out-of-the-box among the 2018 crop of OLEDs - guess I expected lower average and max values?)
I could upload the calibration files if anyone would be kind enough to take a look in case they can spot problems. Just need to know which files to provide
I started with the madVR preset for Rec.709 but with these deviations from defaults:
- enabled white level drift compensation
- added full field pattern insertion (every 60 seconds, for 10 seconds, 0%)
- selected the LG OLED 6-Series correction profile - wonder if I should've went with 'none' instead?
- auto-optimized test chart with 2060 patches, with the "maximize brightness differences" option (think that's how it's labeled)
If any of the above are wrong, hopefully someone will chime in with suggestions
I'm doing another run now, with the same settings but without any whitepoint adjustments - I'm curious to see how the new 3D LUT will compare to the previous one...
