These are no problems… It's simply the way gamma correction works.
Because gamma is the remapping of the linear RGB output to a
nonlinear curve, your RGB values can change radically when
gamma-corrected (especially in the extreme lower-end of the scale).
The 3DS documentation covers this pretty thoroughly, and there's even
a little table of converted RGB values in the 3DS readme.doc that you
can use for comparison (at 2.2).
So, all of the things you mentioned in your first paragraph are
necessary to produce a "locked" target color (except for 000 ambient
light… that has no bearing on the background).
