It's not uncommon for the engineers put more effort into the vinyl mix because it's a much harder medium to get right. It's actually vinyl's
flaws as a medium that make it sound better in a lot of cases as you can't get away with sloppy mixing as much. Things like the "loudness war" (where the industry demanded engineers increase the overall level at the expense of dynamic range - it's why a lot of recordings from the '90s until about 2005 sound absolutely rubbish) just can't happen to the same extent with vinyl, if they tried that nonsense the needle would literally jump out of the groove. It's also associated with audiophiles these days which is another reason modern vinyl mixes often sound better, the market they're targeting values high quality audio more than the average consumer. If you don't believe me, compare the original CD pressing of Led Zeppelin's
Presence with the vinyl. It's honestly night and day.
Obviously this doesn't matter if you're comparing a naff Crosley record player from the supermarket with a naff bluetooth speaker playing 128kbps MP3s. These kind of distinctions don't really matter if your setup isn't great to begin with but it really does make a difference with decent kit. A sound system is only as good as the weakest link in the chain and there's a certain point at which that becomes the storage medium. Overall, a well-mixed lossless file or something like reel-to-reel tape is going to beat vinyl every time in theory but in practice the vinyl mix is often the best.
