Ok, but the lack of a unit on vinyl makes it very hard to have an apples to apples comparison here. If cds are selling 1000 units and vinyl is selling 1,000,000 units, those 16% and 2.4% numbers are pretty wildly different things.
Also, the huge increase is primarily driven by KPOP (in particular, BTS). CD sales growth was like 6% without them.
I don't know that we can draw a conclusion from that 16% except BTS can move physical media.
