Glad to read that.
I've been trying to calibrate Cinema mode for couple of months but no matter what the CMS just did not behave well.
Only when I switched to Custom and everything fell into place in a snap, and the CMS behaves as it should in Custom mode.
A few calibration tricks of mine:
The gamma curve resembles a BT.1886 curve instead a power law.
I use Black Extension (2 or 3) to bring it closer to power law instead of the individual 10 Gamma steps.
Only step 100IRE is tweaked to make the brightest part of the gamma to behave.
I don't touch the W/B 10 steps because I find they destroy the transitions between greys (yes it's because APL +ABL).
I only use the High and Low RGB gain adjustments but very slightly, I find that tweaking the Low gains makes the most difference.
Currently I have -2 on Low Green, that's it.
Strangely enough, calibrating by eye to match my i1-display-pro calibrated IPS panel gave me the best results.
Using my perfect APL picture (keep reading).
I use a HTPC and HCFR to calibrate the screen which is secondary in my OS.
I use the perfect (IMO) APL background which is made of a bunch of small screen shots of several scenes from several movies.
Only then HCFR displays a 1% windows on top of that background which is behind the window ("GDI No Background" in HCFR).
The 1% window is to not effect the APL the background creates.
I use the "Screen Wipe" function as much as I can between measurements for consistency and against image retention.
IMO plasma is the hardest display to calibrate, but after few months of pain, frustration and tears I finally got it.
The trick was to maintain a stable movie like APL, and calibrating using the smallest window.
Here is the background I use for the perfect APL (16-235):
Here's how I do:
Its a 1920x800 version because I mainly watch 2.39:1 movies.
The phone camera can't capture all that contrast (not enough f-stops) which is only on 60.
