Highly doubt it, but it's doing better than most BTS solos do in korea. I think you're confusing where people said it was successful due to V; IU typically doesn't have huge debuts on YT or Spotify and that's definitely due to his appearance in the MV. In Korea, his appearance definitely caused buzz but IU charted high like she usually does.
Ofc YT/Spotify will have the BTS effect, but I didn't read their take as limited to that, instead as a general comment referring to PAKs.
Hence.
