3d LUT calibration is just different way for calibration.. You still have to decide how you measure grayscale..
And this is the key to calibrate the 60s series.. 5% window, 10% window, No APL, 10% APL, higher APL.. you will almost always get a different grey scale result.. And it will always be different with different content.. But the custom mode is the most "stable" picture mode.. best gamma and lowest change..
Even changing the gamma has quite an impact with the 60s series.. Darker gamma and you get a warmer color temp.. I did not see this with 2008, 2009 and 2010 models..
I have read that only the smaller ST60/VT60 suffer from this problem.. Reason could be more power limitations because of size (and also the larger models have more power draw and headroom)
So in theory the best way is to calibrate the 60s series "warmer" as reference and chose a window to calibrate where the green push shows up..
So although not stable it will not reach the range where green is pushed too much so it gets visible annoying.. We are the most sensitive to green and I always calibrate my plasmas rather with green one or two clicks below so I have a nice "Hulk free" image..
There was a huge discussion on avsforum what window size and what apl level to use for calibrating these plasmas and 10% APL level is a very common and recommended setting.. Window size, some use 5%, some use 10%.. I use 10% window and 10% apl and also 10% window with a fixed back ground.. Just to see if there is any kind of variation.. Because the problem shows up with skin tones (faces are usually not a large area of the screen) I can imagine that the ST60 pushes smaller bright parts towards green, to push brightness.. So a rather small window should be the right path..
Right now the S10 with 6000k run hours is my main display, because I am trying to sell it (I have another one).. and then I will deep dive into further calibrations with the ST60..
But it is also a lovely screen.. It is on sale for 60 Euros.. Nobody has interest.. so maybe I will just keep it.. Put 2 plasmas in the basement.. and one to watch..
