The P5WD2 also uses the same heatsink and yet the VRM chip is visible.

Strange...
What counts is not the shape of the chip (i.e. rectangular etc.), but the numbers printed ontop of it. Nearly all chips today are being produced using several package types (shapes). So, there can be different types of ADP3181s for example, that are electrically identical, but look completely different.
