Did an interesting test with THX mode (mid panel brightness but correct LUT's) vs Custom mode mid panel (incorrect LUT's) and the resulting charts were pretty cool:

Folks, I have an issue with GT30 and Viera TV remote control apps, both Android and iOS versions. It used work just fine on my Android phone or my iPod Touch until the TV firmware was upgraded to 2.220. After that none of the mobile device, neither Android nor iOS, running the latest versions of their respective Viera remote control apps can discover the TV.
The TV is connected to wireless home broadband router via Cat5e and phone/tablet/iPod are connected via wireless to the same network.
The funny thing that I downloaded another Android app for the phone called "Panasonic TV Media" from Google Play Store and it finds my Viera GT30 without any issues but the official Panasonic Viera Remote Control App is unable to discover the TV. And that makes me believe that TV is OK but it's the application last updated to version 2.11 on September 10, 2012 that has issues.
Can someone try to verify whether it's working or not on their GT30? Thanks in advance.
Issue is resolved. I have Verizon FiOS and the root cause was in the Actiontec gateway configuration. Verizon pushed new firmware at some point and enabled IGMP proxy. Once I disabled this IGMP proxy all was clear. Now I can use both Android and iOS Viera remote control app. So in case you have experienced the same issue just disable IGMP proxy.
