No one cares because Marvel has a set pay scale and have been jerking over everyone on their first deals. RDJ had everyone's back and lead a renegotiation for the mains during phase 2 so the first wave people are getting checks now. Guardians/Ant-Man/BP still on their first deals. They'll have to come together and drive a hard bargain with the studio just like the first wave did.
Chris Evans only got 300k for the first Captain America. And then got 2mil for the Avengers, which is still crazy low when you consider he and RDJ are 1a and 1b in that movie and it did insane numbers. Only after that did they all get bigger checks. Boseman already starting off better than that .
