well, to decide if the burnt area shows any  burn or  not, I picked up a
verbatim 4-12X CR-RW and  held it at various angles, including an angle
where the grains produced a diffraction pattern. I couldnt see any
difference between the burnt area and the unburnt ring on the inside and
outside.

Maybe its possible to see a mark on a fresh CD-RW burnt with only some
data...
But then after fully burning or  erasing it there will be no obvious
boundaries to be seen ?

Which it might attempt to do and  then totally fail to burn a valid CDRW.

But its  true that its highly  likely that the laser and calibration is
working properly.

Its more likely the burner has a firmware problem  and either a firmware
update or changing the burning mode will fix it.
