An interesting question from a Leela vs Komodo blitz game

Question

In a blitz game between Leela zero and Komodo, the following position came up.

[title "Leela Zero vs Komodo"]
[fen "8/8/2p3k1/4bpp1/2P3P1/4BK1P/5P2/8 w - - 0 1"]

With White to move. Or WHITE King on f3 Bishop on e3 pawns on c4 f2 g4 h3 BLACK King on g6 Bishop on e5 pawns on c6 f5 g5. WHITE to move.

The game ended with a draw, although at a certain point both engines gave quite a high evaluation score. We know Leela is notoriously weak in the endgame. Did Leela zero miss something? What happens with perfect play?

Answer 2

Again , in the following endgame Leelazero vs Dragon WHITE King on g1 Bishop on d3 Knight on e2 pawns on a3 b2 d4 e5 f2 h3 BLACK King on g8 Knights on a7 c6 pawns on a4 b6 d5 e6 f5 h7 BLACK to move the endgame appeared to be winning for White. Analysis 40 minutes on Stockfish 14 NNUE 4 thread , with a second iteration at a critical point. It is confirmed Leela zero is far from infallible in the endgame. In the game, it terminated with a draw.
