Does the physical copy of Evolve’s Ultimate Edition have the dlc on the disc?

Evolve is one of my favorite games of all time. Even with the serves down I like hopping back in every now and then. Recently however, I noticed that all the DLC characters, which I previously bought, are now locked. I researched the issue and it sounds like the only way to get those characters again is to buy a used copy of the Ultimate Edition for Xbox. Is it true that the disc has the DLC characters on it, or did the Ultimate Edition release with a download code?
