I, too, agree that that effect can exist.

I maintain that the lathing treatment works on my system; my discs have been done very economically, not by myself.

The cds I listen to are listened to pretty regularly and I know what to expect (generally).   The improvements i have experinced range from the subtle to quite dramatic benefits in detail and sounds staging, such that my standard discs now sound (noticably) a bit lifeless.

So, i don't altogther agree with you summation Ian, as I now have to get the rest of my discs lathed or they will irritate me intensely!
