The another long 0.00 score was correct here
When Stockfish had played 47.. h5! Or 47..Bd8! white cannot win and rather could have prooven Komodo's 0.98 too optimistic.
Point is the control over the two free a- and e-pawns
With bishop on e7 and black king on queenside white cannot intrude with the king to chase the bishop away because of the threat of the pawns on the kingside. Nor can enter with the white bishop to support the e-pawn so in the end draw
