The Dolby format should be available in more places, too. There’s now TrueHD audio bitstreaming when you’re playing console games, so titles that support it can pass that audio directly to your receiver for decoding. You’ll get the benefit of TrueHD if you’re using a supporting sound bar, as well. You might not necessarily notice the difference from going lossless (especially if you’re using built-in speakers), but look at it this way: if you’ve already paid a pretty penny for an OLED TV, it only makes sense that you should get the no-sacrifice audio to match.
