[tex]w = \frac{\dot \phi^2/2 - V(\phi)}{\dot \phi^2/2+V(\phi)}[/tex]

becomes eventually indistinguishable from -1.

Shouldn't physics stay invariant in this case?

yes,this potential is some quantily of energy density deimension and have absolute value to curve the space time.You can't redifine it by adding a constant. It is an extensive quantity right over there.
