DL switched from using W fares to P/A/G fares for Premium Economy fares on VS not too long ago. They also got rid of S coach fares. It just looks like they haven't bothered to update the website as it still lists W and S fares as eligible fare classes. So I would expect your fare to be eligible even though the website does not list it.
