So perfect play is a tricky so allowed the engine to play it out.

Analysis

A review of the position using StockFish 14 indicates that White is winning with a positional advantage of +-1.51. This was discovered at a depth of 40. I ended up running this to a depth of 120 at which point the position was drawn. I went backwards to find the critical position where this occurred and stepped a bit more forward for explanations sake.

Conclusion: The position is drawn and with perfect play White has no ability to convert this to a win.

If you look at the above at move 14. it become apparent what the issue is. Black has only a King, but white has a Bishop (Light Squared) , Pawn and King. The pawn is on the H file. White cannot stop the black king retreating to the h8 square where it can force a stalemate or draw by three fold repetition.
