No Way Home was also a sony movie.It's a useless hypothetical to make is my point considering the fact that Tobey was under contract with Sony and RDJ is/was with Marvel/Disney outside of his appearance in Homecoming, so whose to say that RDJ wouldn't get close to the same amount again especially if it's a situation where they're desperately in need of his character.
They both would still be working with the same company that offered the initial big contract.
