There is a chance you snagged the 50PF50 I also had my eye on if its the low priced one listed on ebay a few days ago. The listing ended early so not sure what it actually sold for but if you managed to get it near the opening price you have probably the best bargain pro plasma around!
Glad you like the black levels and also the stability. There is still hardly anything that gets me down about the PF50, its weird. So sad that there will never be a PF60 or any more Panasonic pro plasmas.
Anyway, I do also find colour needs to be set down to -5 or so like yourself.
No CMS sadly, just the high and low white balance as you will have seen in the options. You can also adjust RGB drive and RGB cutoff in the service menu but no 10 point adjustment anywhere that I know of unless there are some secret hidden button presses to unlock them- but I doubt it.
For whats it's worth, and it's probably not much, these are my current settings, (these are just my preference by eye on the 60" model and not professionally calibrated):
Brightness: 0 (I try to set up the low white balance so this can stay at zero)
WB High R: 0
WB High G: -15 (minus fifteen!?! - always far too much green at zero on every PF I've used )
WB High B: -12 (sometimes vary this if i want a slightly cooler blue for videogames)
WB Low R: + 5
WB Low G: -1
WB Low B: + 5
-15, and -12 seems crazy, but after hours and hours trying different ways to get a picture I'm personally happy with, blue and green always have to be offset down to get a neutral grey shade using warm.
Anyway, glad you're liking the PF50 and can corroborate a few of my own findings.
I just got a 42pf50u too! It's a US version though
A couple things to note.
While There might be differences due to EU energy saver modes, but on the us version, with all power saving stuff turned off, and peak limit off:
CINEMA mode seems limited to only about 20FL
STANDARD mode will reach up to 35FL at the full +30 setting
(I have mine set too +25, which give a perfect 100cd/m2 reading with a small white box pattern)
As for gamma, I'll attach some screenshots later of some rough out of the box readings, but 2.2 is was too light, 2.4 better, and the 2.6 setting reads the closest to 2.2!
So I would choose Standard mode, gamma 2.6
With the gamma change, you need to raise Brightness up - mine's at +15, but I haven't fine tuned it in yet. It might still be a touch dark.
(Yes, It seemed perfect at 0 with the 2.2 gamma setting)
Also, I turned OFF the Advanced Motion Resolution setting, as It seemed to be causing th strange soap opera effect..
I had the Frame Creation turned off from the start (not sure what this does)
Also, I disabled nanodrift.. Yuk!
Pretty great so far!
I have contrast at 20 and this produces about 21ftL luminance. This can be upped to about 24ftL with contrast at 30 and ALL_DRV maxed out in the service menu but the whites are then too bright for me. Gamma at 2.4 gives me a great 2.25 average gamma but I do have a spike upwards at 90IRE which I can't seem to shift (10IRE to 80IRE is pretty flat). In dark room viewing, Cinema mode with contrast at 20 is perfect.
I also calibrated Standard mode to about 30ftL (35ftL is too bright for me) and it also requires gamma to be set at 2.6 to get a real 2.2
