if you take the same master and play it vinyl vs. highest quality FLAC, will you hear a difference? if you do, what kind of things will be apparent?
It’ll sound different.
For a lot of reasons, you’ll hear the effects of the Cartridge, the tone arms tracking, the Phono pre-amp, the turntables speed accuracy.
But even without those there are things turntables can not mechanically resolve, for example they cannot resolve low bass notes in stereo.
