Dirty peep-boy screen (Fallout 4)
It doesn't look like dirt. More like a bug. When you just picked up the peep-boy and the character played the animation of "crushing" the dust, it didn’t disappear.
I had such black spots on the old Nokia when I dropped it on the stairs.
Delete the second topic.
Try the following (found the comment right there):

"additional lines in Fallout4Prefs.ini:
Additional lines in the [Pipboy]
section New [InterfaceFX]
[Pipboy] section
; your settings plus those below
fBlurRadiusPipboy = 0
fBlurIntensityPipboy = 0.00
fScanlineScalePipboy = 0
bEnableFlickerPipboy = 0
bUsePipboyMode = 1
[InterfaceFX]; is a new, not previously existing partition Fallout4Prefs.ini, you can copy and paste it to the file
[InterfaceFX]
bEnableFlickerMenus = 0
bEnableScanlinesMenus = 0

UPD :
Also: in the game console, write rimod 00094636. Not the fact that it will help, but already something
UPD2:
This should be your option: http://gamer-mods.ru/load/fallout_4/interfejs/pip_boy_uhd_4k/130 -1-0-3594
Install with an emphasis on "Blank Screen".
