Can you exclude that your vinyl is mastered differently? To my ears, this is often the case.
The mix down to 16/44 for the CD master requires conversion from either 24/192 PCM or 24/96 PCM (rarely DSD or 2x DSD, or DxD). The LP master would be cut be on a lathe directly from the final mix files which is a whole other digital to analog conversion. This all depends on when the recording was made - I'm referring to the new issue stuff like:
Arctic Monkeys - 'AM' and 'Suck it and See'
Black Keys - 'El Camino', 'Turn Blue', 'Attack and Release'
The 1975 - 'The 1975'
Taylor Swift - '1989'
Lana Del Rey - 'Ultraviolence'
Spoon 'They Want My Soul'
Some of these even come with the CD wrapped in the package.
Hopefully one day we'll get a blue ray with a copy of the 24/192 PCM file.
The issue is of course high quality pressed vinyl is way more information dense then a 500MB 16bit 44k sampled CD.
Not to mention all the phase shift and ringing issues with the brick wall filters in the playback chain on Redbook. Vinyl of course has it's own set of issues - but the best vinyl playback gear goes along way to mitigate those issues. Hence the huge resurgence of vinyl in high end audio.
Here is a very good white paper that compares Redbook to DxD.

PS There are estimates that a modern high quality 180gm LP has the equivalent of more then 1TB of bit density - depending on the ability of the Cartridge to exact that from the analog grooves and to suppress or lower the surface floor noise. On modern well pressed 200gm or 180 gm virgin vinyl the floor noise is almost non-existent (below normal ambient room noise).
