If one wants to stay within the 'philosophy' that resistance is a
temperature and geometry dependent property of the material, then what one
would say is that the light bulb has a well-defined resistance for every
temperature encountered within a given range of currents. The I-V graph is
then a convenient way to MEASURE this resistance. ;-)
