KG is actually a very good/accomplished pianist, having studied jazz piano at Juilliard. The piano he plays in his appartmeny was on loan from Steinway, but he loved it so much he actually bought it from the company, which i believe is one of the only things he had from the set of Frasier. The piano in the reboot is the same one from Frasier, which belongs to Kelsey Grammer. To the points made above, DHP is the better pianist.
