Thanks to all ; this is very enlightening, and the only portion that is not confirmed is the ISO compliance of the Merrill-based cameras.

Considering how they treat color management, I assume that ISO compliance is not one of their main goals

To be more serious. Its my experience that different camera brands expose differently. So, they cannot all be ISO compliant. Moreover, the ISO compliance can only really be useful for spot metering. The averaged metering and the multi area intelligent metering do whatever they are programmed to do, which of course varies from camera to camera.
