I turned the white balance on based on an ISF calibration post I saw, before doing WOW. I saw your settings, and went through mine twice because of the differences. However, I have not done a calibration on my previous plasmas so it is pretty new to me. There seems to be no difference in a lot of things for example colour 49-53 look the same to me lol.
I was surprised by the contrast setting but did it about 10 times and with it fully turned up , I could clearly see the middle showing good white and the 3 lines on the left showing as per the instructions where it says you should see AT LEAST two. I have sharpness at 12 too, which is higher than yours but again, I couldn't tell any difference between small tweeks, but could just about see a diffeerence between say 12 and 30
