Today's recordings are all high-res digital masters. Releasing them on vinyl format isn't meant to improve the sound quality at all. From the artist's and label's standpoint, vinyl releases (limited or standard) is to make a higher profit margin per unit sold. The sound quality of vinyl, even today's vinyl won't be as good as the high-rez digital recording because vinyl has medium format limitations. This is why recent vinyl remasters and even new releases will have a compressed dynamic range to fit the format or the producer's remastering goals.
CDs don't suffer from the same dynamic compression issues that vinyl does because the format can hold more information. A caveat to this is when you have a double vinyl release that has 2 or 3 songs, max per side of vinyl. In this case, they're allowing the vinyl the opportunity to show its potential as a music format.
I also think one has to be aware when buying either vinyl or CDs, of the time period in which the original recording was released. Pre-CD ear, many albums sound better on vinyl, post CD-era when vinyl releases were going away, the original CD release will sound better than a post-CD era vinyl re-master.
Then there are examples of my recent digital purchases of high-res recordings when I buy the CD. I've listened to both and they sound identical in soundstage, dynamic range and clarity.
My recent vinyl purchases tend towards completing an artist's catalog in my collection or original used 1st/2nd pressing vinyl. I don't prefer any particular format over the other because when I'm critically/purposefully listening to an album, I listen in the best format that I have.
