Let me just weigh in on this here - there should be absolutely no difference in sound quality between TrueHD, DTS-HD MA and LPCM. The former two are both lossless and are therefore identical when uncompressed to the latter, LPCM. In fact, if your ultimate goal is to achieve the best sound quality possible without sacrificing picture quality, then TrueHD or DTS-HD MA are the more desirable options over LPCM as they result in the dentical sound quality in less space and with less bandwidth.

Personally, I would prefer to see the Blu-ray studios abandon LPCM on all film releases in favour of either DTS-HD MA or TrueHD in order to optimise picture quality. For something like an audio-only Blu-ray release, then LPCM is perfectly acceptable.
