No. That simply has never been proved. The supposed AUDIBLE improvement in two-channel sound by virtue of increasing playback sample rate and bitdepth, or by switching to DSD, has no firm scientific validation.
IMO vinyl, SACD DVD-A have a smoother easy to listen to sound that CD, MP3 lacks. You can't hear it sometime and sometime you can, but you can certainly listen longer without fatigue.
No, that's not 'certain', that's an anecdote. There's much more evidence that if you made a good mp3 from that LP, it would likely sound the same to you.
One more thing is that CD's are ussually compressed more due to many factors I do not agree with, but one reason is that CD's lack low level linearity due to lack of bits.
This is a canard. Never heard of dither and noise-shaping? It's only been used for, like, a couple of decades now for CD releases. CD has no issues with 'low level linearity' in this day and age. If you are really worried about resolution of low-level signals, you'd stay as far away as you can from LP.
