Atmos objects are only available as "metadata" added to a TrueHD or DD+ bitstream, not LPCM. No current BD players can decode Atmos, so they can't send it as LPCM, either. (Maybe the next generation of Oppo players might.) For Atmos objects to get to a receiver or pre/pro, the Dolby audio tracks have to be "bitstreamed" from the player to a decoding device. In other words, Atmos is "compatible" with any BD pleyer which can bitstream TrueHD or DD+ audio tracks. As a result, the original "Fat" PS3 can't pass Atmos objects, but all other Blu-ray disc players that I'm aware of can.
If you don't have an Atmos decoder (in a receiver or pre/pro) you'll hear just the "bed" lossless 5.1 or 7.1 audio tracks, so to that extent you don't need to upgrade. I dunno if the audio that Atmos objects would have sent to the overhead speakers are folded into the bed audio in a way that PLIIz could redirect them to front height speakers.
