CD masters rejected for vinyl production

It will have a higher resolution. It is highly unlikely to be of audible higher quality in a comparison between properly produced Blu-ray and CDDA versions of the same master of the same material. Bigger numbers don’t mean anything for audible quality. Talk of quality is irrelevant beyond the threshold of transparency for any given combination of material and user. Once you can’t discern between a stream and its original source (e.g. master), that’s 100% quality as far as audibility is concerned, and big numbers aren’t relevant at all. Don’t be fooled into believing they are by marketing or subjective reports from highly impressionable users elsewhere.
