I think they are the same sulphide, but yes, the lighting will have quite a remarkable effect on the view of any sulphide weight. From one angle of light, features will appear flat, yet at another angle they can be "extreme". It's often difficult to achieve a photo euqiavlent to natural viweing because when viewing normally, the brain sorts out a lot of information based on assumed visual apsects and on lighting from overhead, not directly in front on to one side.
To me, wrightoutlook's weight always seemed closer to Garfield than Grant because of the "ridges" in his beard over the front of the chin. In all images of Grant I have seen (mostly on the web), his beard at the chin has not had vertical "ridges".
