Thanks a lot, Bruno! Using build_patches(2) on the coarse mesh (I am using linear elements) the two interpolations look much more alike.
Since I will need to do the same transformation several times for different vectors, I am coming back to my other question: Is there a function that uses the std::vector<std::map<.,.>> of DoFTools::commpute_intergrid_transfer_ representation and makes some sort of transfer matrix from it? According to the documentation, there is such a function. But according to the docu, the output of compute_intergrid_transfer_representation is still a matrix so I am not sure if I just missed it or if it does not exist since the docu is out of date.
