Libraw's -4 option is different from dcraw's -4 option

(v. 0.16)
dcraw -4 -T filename.nef
dcraw_emu -4 -T filename.nef

produces different results, as does the '-W' option (which is also enabled when using -4 option).
Could it be that there is still some kind of auto scaling enabled within dcraw_emu, because it brightens consequtive images differently some times, while dcraw does not.
