DoVi profile 5 black color change

[madey83]

hello,

recently i've try to re-encode tv show with dolby vision 5 profile and when i use this [neo_f3kdb] with these options:

neo_f3kdb(range=15, y=65, cb=40, cr=40, grainy=0, grainc=0, sample_mode=5, blur_first=True, dynamic_grain=False, mt=False, keep_tv_range=True,output_depth=16)

the black color change to grayish.

on below screen there is visible different on the color. On the left encode without filter, on the right with above settings

You wrote "encode". Does the issue exist if you just open (AvsPmod/VirtualDub) the avs script?
