I'm not sure I'm a strong enough player to assess this endgame but I have dabbled in the Chigorin and often gets this kind of position in other openings too, so here we go:

Black's pawn structure is very compact with few targets to attack for the white bishops.

Whites light squared bishop is "bad" because of the pawn at c4. If this pawn advances to c5 it will impede the dark squared bishop as well as being a target of attack.

Black's knight on f6 is quite stable, it will not be easy to chase away. As long as it remains on f6 the h7 pawn (and with it the entire pawn chain) is safe.

White cannot easily challenge Black's stand in the center. The f4 break would only result in giving White isolated doubled pawns.

So what is White going to do? Put a bishop on b2 pressurizing e5 perhaps, but this point is easily defended. White's position seams lifeless, so =+ looks like a fair assessment to me.

What do you endgame gurus say (Micawber?).
