Below represented tech specs of both streams:
| Duration (min:sec) | Bitrate (kbps) | Size (mb) | Channels | Bit Depth | |
|---|---|---|---|---|---|
| DTS-HD MA | 02:21 | 4006 | 68 | 6 | 24 |
| DTS Core | 02:21 | 1509 | 26 | 6 | 24 |
From 6 channels let's pick up front center (i.e. FC) as a lead channel. To find the sound leftover, it will be enough to subtract DTS Core from DTS-HD Master Audio. The difference spectrograms will look like:

Audibly, what is left is sort of high-frequency hiss/noise around -80 dB, nothing important or audible.
