confirming lossy DTS core from lossless?

[billsantos]

I have been using eac3to to extract what I thought were lossless tracks from a DTS Master Audio 7.1 ch track. I have the output set to wavs and I do, in fact, get 8 mono wave files, all 24 bit, 48 Khz with 1152 kbps bit rate. Now when I do this same process with -core at the end, I get 6 audio channels of wave files, but in the file specs, they are also listed as 24 bit, 48 Khz, 1152 kbps. When I listen to the audio tracks, they sound the same fidelity wise, so I am wondering if I am really getting lossy or lossless depending on what command is used? How would I check for sure? thanks.
