Yea, vinyl sales are like less than 2% of
all album sales in the US. So literally
98% of US album sales are NOT vinyl. That's no comeback at all; maybe 20% or so would be respectable, but still very much a minority.
Got no idea why this should be happening.
The late 2000's to the present "hipster" trend. After that goes, (soon please!) so will vinyl.
There are, however, "audiophiles" such as myself who are often forced to buy vinyl for newer albums (since the mid 90's) since, for some infuriating reason, the vinyl version of albums often has a higher DR than that of the CD which often have DR levels in the single digits (which results in pretty horrid sound) starting in the mid 90's thanks to the LOUDNESS WARS.
Now,
why the CD or other digital versions often can not have the
same DR as the vinyl I don't know (though I wonder if it is some kind of nefarious marketing on the part of vinyl manufacturers to target the "audiophile" market), but for favorite albums at least, I often have to buy the vinyl version (and then rip it to FLAC) to attain a decent SQ for that album (and also put up with all the surface noise).
You can compare DR levels of different formats here for an album:

Plus, downloads have diminished the relevance of CD.
Not for me, especially since you can't really even trust many download sellers to be giving you a lossless file instead of labeling lossy as lossless. I'll always prefer the tangible copy and knowing I ripped the CD to FLAC myself.
