More or less, yes.

I have other files. Some with 24-Bit DTS-HD and 16-Bit DTS Core, some with 16-Bit DTS-HD and 24-Bit Core and last but not least 16-Bit/16-Bit as well as 24-Bit/24-Bit. I just re-checked with MediaInfo and even for (lossy) DTS I get a Bitdepth shown.
Lossy DTS (Core) don't have bitdepth, and MediaInfo is wrong when show that info (and others infos).

I read that based on the bitrate AC-3 limits the available frequency range, eg. 256 kbps up to 12 kHz, 384 kbps up to 18 kHz and 448 kbps or higher with full 20 kHz. Is that true?
Is a encoder option, but is recommended for 5.1.

For 2.0: 112 Kb/s up to 12.4 KHz, 160 Kb/s up to 15.8 KHz, 192 Kb/s or higer up to 20.3 KHz
