Other that what lights up on the receiver, there really shouldn't be any difference in what you hear. Both players in question are decoding TrueHD, DTS MA, etc into LPCM and sending that multichannel DIGITAL information to the receiver. The receiver still handles the final D/A conversion and can do bass management, etc just as it should.
This isn't like the days of DVD being a new format, where having a digital bitstream from the player to the receiver was the only way to let the DACs in the receiver do the DA conversion of the multi-channel audio.
Anyway - just trying to save you the hassle of a return for something that shouldn't make any audible difference at all.

But the packed audio formats have to be DECODED back into PCM before you can really do anything with the audio. For Dolby TrueHD and DTS-HD MA, the decoder could be in the player or it could be in the receiver. In either case, what comes out of the decoder is a set of PCM streams -- the IDENTICAL PCM that went into the encoder in the studio. The technology licensing from Dolby Labs and DTS insure this.
