What have you set your output to, if not PCM? You might have to explicitly tell the player to bitstream. If your 01 is displaying PCM, that's what it's getting.
On the other hand, you're right. Decoded PCM is identical to the lossless codecs. You're just moving the decoding from the player, into the AVR.
This whole business of THD and DTS MA decoding in the receivers is highly suspect anyway. It used to be a necessity back in the day, because there was no way to digitally transmit the decoded DTS/DD tracks, so you had to bitstream them via SPDIF, or use a 5.1 (or 6.1) analog connection. Nowadays with HDMI capable of multichannel PCM, there should
be no need for bitstreaming, or at least it shouldn't be nearly as important as most people make it to be.
I say "should" because with some software players, they deliberately, or having bugs, mess with the sound, and the only way to be sure to have undisturbed audio right now it's to bitstream, but that's a workaround to a different problem bitstreaming just happened to come in handy with.
