Does polytropic or isentropic expansion lead to better retention of steam quality?

Question

Nothing complex here but I am revisiting some old thermodynamics fundamentals. I want to keep steam quality high (drier) in the steam turbine. Does inefficient expansion (which is typical) lead to better final steam quality for a given temp and pressure change? When I map it on the T-S diagram it makes sense but I need some confirmation here.
