To be completely honest: no
it would be a lot of fuzz and there aint much to see.

there is one simple bulge in the main plate causing a none planar hatch door. this breaks the shading a little bit.
and the ring uses one champhered extra line at the edges with another set of smoothing groups. this way the very low end of the hatch as well as its edges will be a little darker then the rest.

thats all there is.
and as said, if you dont like this you can remove them very easy from nmap.

have a nice one
