As Anthony points out in comments, Two Hands only scores 2.0 audio. Which is probably due to the movie producers keeping the budget down.
The title presumably wasn’t big enough for Icon to spend a lot of money redoing the sound, so that’s how the Blu-ray was presented: as 2.0.
Unlike, say, Warner Bros (which often uses Dolby Digital in these cases), Icon chose to use a lossless format. It isn’t at all important, but I’d suggest they used the wrong lossless format.
Any guesses why I might think that? You may need to check the specs to see why.
