Since the number of positions expands expontentially with each ply, and since you must prune most of them at further plies down the road, I would guess that the curve definitely flattens as the time control increases. To the extent that your eval is imperfect, I would guess it flattens quicker, so that the slope of the line shifts to be more horizontal than vertical in different places for different programs.
