Buried capacitance is typically just a thin layer for improved sheet capacitance and used primarily for supply decoupling. As such, it's not really a relevant circuit element for reverse engineering. I've yet to see a consumer board with a buried resistance or capacitance layer. Nor have I seen discrete components somewhere in the laminate. Even things like rigid-flex or nonuniform laminate stacks across the PCB are extremely rare. Not even my cell phone has has such fanciness. Looking forward to tearing something apart that does, however!
