No Tiger did not had KRP-KR installed, you can see it on the Tiger's wrong
moves (88.Ra7??) Gandalf on the contrary has the good mate scores and moves
as a result of a correct set-up of the tables bases. Here is the game.

Have a look at Gandalf's -M28, -M27 mate values coming directly from
the KRP-KR TB.
88.Ra7? is the move that gives away the win. Tiger with an installed
KRP-KR TB would not play this.
