I have 65VT25, have done DNICE break in, SM Offsets and his settings. Picture in 2D is very good. I just did the 3.5 Firmware update with USB device, I had one glitch at the very last step after intialization the TV turns off auto then is to turn back on in 10 secs it didn't seem to do so. I redid the upgrade and this time it did but it was very hard to tell the screen is very dim, but I notice the red light back on, so it worked. I did the 3D Custom settings. I viewed Cloudy with Chance of Meatballs, the picture was excellent, popped of screen, very vibrant with great detail, I am very impressed.
Another minor glitch, when I tried to play 3D, it came up in TV that I have to have 3D TV and player which I do. I turned off and back on and all was well. It didn't change any 2d settings however I haven't had a chance to watch 2D, will do so shortly. Very happy...
Watch Lord of the Rings Twin Towers, THX mode with D-NICE settings somewhat Tweaked for more pop, picture was still outstanding, it was probably just me but the picture even seemed better after 3.5
