sadly, the light prevents every attempt of comparison, and its shape isn't clear at all, we can only "imagine" it:
HEY Glad to see you back!! Hope everything is okay
I thought maybe THEY came and got you
Here is the best I can do from the MSSS strip... The USGS one looks like a different angle, so they must have shot this one twice even though the image number is the same..
Have a look at this closeup and tell me what you thing...

As to the "spotlight effect" take the image above and put in in your graphics program... (I use thumbs plus as it has a slider control and you can watch the changes) Increase the brightness quickly... you will see your 'spotlight effect' There is only one crater in that field but the sun angle is from upper right... the effect definitely appears to be coming from the object
I will try to make an animation later
In the USGS version there is no detail at all in the blacked out area... but you can see the sun angle in the small crater... You can also see the angle of the light from the object... this one is even more dramatic in lightness change
