>>4484570You're overthinking it. Mono APS-C is probably close to if not on par with full frame color when it comes to the stuff you mentioned.
However at least to me the main draw of shooting native B&W is using color filters. With the GR series this is only possible using the filter adapter which deletes the main draw of the GR, that being convenience and pocketability.
