Regarding the hi-rez mode of the E-M5ii: Afaik there is the option to save the image as a 64mp RAW file which only contains about 40mp of information (thus 40mp JPEGs) and can only be processed in photoshop with an extra plugin from Olympus. If the workflow is already Adobe-based, it shouldn't be too much of a problem.
The parameters for the RAW conversion are calibrated according to a specific value in Imatest. We take a high performance lens at its optimal settings and go for a unified value here.
The reasoning behind this is to equalize the effect from the AA filter of the camera, internal processing within the camera as well as the impact from the RAW converter (bayer interpolation etc.). If you don't do that the variations between the systems would just get way too extreme resulting in unreasonable data.
