Usually the receiver will indicate if the sound is DTS-MA or TrueHD, but all mine says is MultiCh 7.1.
The option for bit-streaming for games and for movies are separate. When a movie is playing, press the Option button on the controller and go to the settings menu there.

You are not losing anything with Multi CH 7.1, you are getting the full audio signal on movies...
Pretty much the opposite happened for me.
I had lip sync issues with quite a few movie Blu-rays. I forget where I read to do this, but changing the 1080p/24Hz option in the main settings menu from "automatic" to "off" seems to have fixed this.
Out of the three games I have (Assassin's Creed IV, Killzone, and CoD:Ghosts), I only had audio problems with Ghosts, and as mentioned in a previous post, I think that was more a poor sound design choice to not use the center channel for much than broken audio. The other two use the center channel as you'd expect.
In that thread at Sony, it seems lots (although hard to tell when a relative few out of 2 million PS4 owners posting) also had issues with audio not working, especially over the optical output.
I wonder if milehighou checked Killzone to see if that game worked.
