All three that you mentioned can have different bit depths and sample rates. Once the losslessly compressed formats are decompressed, they are in PCM format. The advantage of the losslessly compressed formats is that they take up less storage space on the disc and have a lower transfer rate than PCM, thereby allowing more space and transfer rate for the video.
It is odd that the majority of discs you have looked at are PCM because DTS-HD Master Audio has become the de facto audio standard for Blu-ray. Currently the codec is used for nearly 48% of the discs that have been produced so far. Dolby TrueHD makes up about 21%, PCM about 14% and the rest are lossy codecs (DTS-HD HR, DTS and Dolby Digital).
