Every program I've tried so far seems to think that this position
is won for white. There are evals of more than +3.00. White is a pawn
up but it's a dead draw.
White's king has three doorways to heaven, a5, c5 and e5.
But black's bishop is closing everyone of them:
1) The white king moves to a4 and tries to enter via a5.
Black keeps the bishop on c7 and shuffles the king.
2) The white king moves to b4 or d4 and tries to enter via c5.
Black puts the bishop on b6.
3) All the time black prevents the possibility 1.e6 fxe6 2.Ke5
by keeping the bishop on c7.
4) If white plays his bishop to f4, threatening 1.e6 black plays
1.-Bb6. Then 2.e6 fxe6 3.Ke5 is met by Bc7+
5) And black has a million of Kg8-h7 moves while white cannot make
any progress at all. 1.Bd6 Bd8 is nothing. All c5 moves from white
are just voluntarily closing one possible path for the king.
