Hmmm, I wouldn’t go towards this direction to differentiate releases, simply because some stores provide hi-res FLAC or ALAC albums made from low quality (heavily compressed) MP3s, and some stores provide very high quality MP3s made from hires studio masters. Plus the name of the format alone doesn’t mean much (resolution, number of samples/seconds, compression algorithm, compression level, lossless, are to be taken in account when one wants to compare formats).
