For a valid test using dxo ISO, you say I should use camera iso of 3200 on the OM-D and 1600 on the G3. Why wouldn't I just use the 1600 on the OM-D as well and reap the benefit of running a lower iso

You could, but then you would not be recording the same tonal range, breaking your photographer's intent and therefore no longer comparing apples to apples.

(and enjoy being able to meter correctly too)?

This discussion has nothing to do with metering. It's about comparing cameras/sensors apples to apples.

Meter as you please to achieve your objectives of maximum signal and IQ possible - within your self imposed blur, dof and highlight retention photographic constraints.
