It appears we have no public interface to check whether the grid is on? Downstream libraries are now replacing the privateself.xaxis._gridOnMinor with the privateself.xaxis._minor_tick_kw["gridOn"], which seems even worse.

Seems we needself.xaxis.grid_on(which='minor') andself.xaxis.grid_on(which='major')?
