I have just seen the proof, that there is no real ISO gain on the D3 for the setting 100 (and probably neither for 125, 140 and 160). When ISO 100 is selected, the effective gain is at ISO 200. The raw data reflects this higher exposure, i.e. the camera does not adjust the raw data (in contrast to the fake high ISOs).
The consequence is, that using ISO 100 with auto metering overexposes the shot by one stop.
The overexposure will be compensated for in raw processing automatically (in ACR as well). However, the compensation won't help on clipping caused by the overexposure.
