Season pass

An important question arose: I purchased the game at the time of release, but I bought the pass already for season 2 and, accordingly, did not receive ultramarine cosmetics specifically for support. But when a friend bought the game in full with a pass, he got both unique skins and angels for bastion and Ultramarine for support . The question is, what's the bottom line? If you buy the game immediately with seasonal, then absolutely everything is rewarded, and if you buy a pass later, then not all the rewards? or I have a bug.Steam says to buy DLS for this skin
