My UHD722 is much more stable now, AppleTV still takes a little bit of time to sync up between resolutions and color depth changes which is to be expected, but it never completely locks out and just loops with black screen like before. AppleTV has been the biggest offender as every other device I've had connected, be it Bluray players or gaming consoles have never had any issues.

The biggest problem I've experienced that seems to not yet be resolved is that sometimes it's like my G65 can’t quite lock onto the audio signal and blasts me with really loud white noise for a couple of seconds before stopping and syncing up with whatever is being played on screen. The G65 display shows it's trying to figure out which signal it is and changes briefly between pro-logic and cinema modes. This only occurs when I'm using my AppleTV which is frankly so frustrating I almost gave up on using it till this firmware update.

I am currently using the stock AppleTV cable which could be purchased along side the original AppleTV 3. generation back in the day, I'll give it a few days with my Audioquest cables and see if that helps, would be such a relief if it's just a cable issue, but I remain skeptical.
