You don't get a sign-on bonus every year either. Agreed, I'd say at most you're getting $250k/year in equity, no way L6 is getting $3.2M in equity over 4 years
The sign-on bonuses are amortized over the equity vest period (which is a bizarre way to do it, but whatever). Aggressive L4 offers can clear about $250k/year in equity, so I don't know where you're getting this "at most" quantity...
