Most of the monitors to which I have applied this darkening technique go
completely black if the EVS and NVRAM levels are set to zero.  I have seen
one monitor which did not completely blacken and it had been tweaked
because it was growing dim.  So, I don't think there is much danger that
a properly adjusted monitor will suffer login box burn-in unless its
intensity hardware has been adjusted.
