add a comment. also, i think it's confusing to use "Native" here. in other
contexts, like ui/gfx/native_widget_types.h, "native" means platform-specific. i
think that something like IsPhysicalDisplay() or IsRealDisplay() would be more
appropriate here.

Done. Moved to IsPhysicalDisplayType() with an appropriate comment as. The Type
suffix as it does not take a display but instead the connection type.
