Picture of female Line screw head from Wikipedia overlayed in red on your screenshot:
Looks more like a female Line screw head to me, not that I know anything about screws. According to Wikipedia Japan likes to use them on IBM computers, and Nintendo consoles. Samsung is Korean, but point being some tech companies do use Line screw heads. I'm not sure what size you'd need, but there are only 5 sizes (ALR2, ALR3, ALR4, ALR5, ALR6), and you can get 5pc sets.
