It's the way our vision works, not the flashlight (mostly).

High intensity/white light flashlights can induce more of the first image, but even those don't make a hard transition of visible/not visible, as light splashes and our vision has a gentler transition.

I own both cheap flashlights, good ones with high CRI, some with high intensity and high CRI, some with high focus, etc. Pretty much all of them produce the second image in varying degrees because that's how human vision works.
