I use Vivid with colour temp 2 and colour is dropped a bit to 45. Brightness is 0. I don't use THX cinema. I used S&V settings for a while but still feel black levels are raised. However on very bright scenes or some bright mid apl scenes the wide screens will appear to vanish which is a nice touch.
I don't think a full calibration would deepen black levels at all. It would increase accuracy of gamma but black levels majority of the time will always stay the same unless the owner doesn't have a clue what they were doing with settings and had brightness raised all the way past +10
Im assuming Panasonic wanted to achieve maximum peak brightness in 3D mode so brightness was raised as well
FWIW, I can attest that watching a 3D movie on the 65ZT60 is like watching a movie in a cinema. The image isn't very bright but its good enough. Its VERY easy on the eyes just like a cinema experience is. There are moments in scenes where even a glimpse of the sun or flashlight or explosion would momentarily be bright enough for me to squint my eyes so as not to be blinded
Vivid... like I said when I first tried 3D early on I got cartoon colors (I'm thinking with default out of the box settings, but maybe not)... would prefer realistic colors, can't imagine Vivid would provide them regardless of 2D or 3D. S&V was much more realistic than my prior settings.
But from recollection, you may be right, I have a vague recollection of some washed out black levels here and there, but for the most part, it's 3D, it's not going to reach 2D PQ on this set, so given it works pretty darn well (from my fairly limited, quite a while ago experience), not a big issue for me. If you have Prometheus 3D, give that a look, that's the last thing I partly watched. Lots of blacks to play with. (Have a couple newer ones to check out, maybe next couple weeks I'll finally get around to them.)
[I've never seen 3D in a movie theater, fwiw. About 4 or 5 blu-rays to date is about it.]
