I think that more moves are needed to decide about a draw

You can see that the main line lead to trading the pawns(white f6 and black e5)
and it is possible that after it fruit can get 6 piece endgame that it can win(I
did not check tablebases)

More analysis give higher score for white and if the operators agreed to a draw
only because of many moves with no progress then it is clearly wrong
