Will the license for the new upcoming expansion for Ghost Yotei be on the disc or a code in the box?

I have the standard edition disc. My idea is to sell my disc to Cex and buy the complete edition, if the licence for the DLC is on the Disc instead of a code to redeem it on PSN Store.

But if it indeed is a voucher code I'll just get the complete edition upgrade on the PSN Store.
