You can't assume that---especially as components age.
It's not an issue if you're only displaying video that
already has overscan built into it, but if you have any
computer-generated components in your display (windows
or decorations/borders, parts of the UI, etc) you will
definitely see asymmetry on some sets.  Even some new
sets.
