- no visible benefit in keeping ISO at the low read noise minimum (800 for this sensor), and possibly struggling with a dim view/LCD in camera, and raising brightness later.

I'd be very interested if bobn2, Great Bustard, Gollywop, Detail Man et al would agree?

It depends on the scene. If the scene has a higher tonal range than can be handled by the 'correct' ISO, then there is advantage to using the lower ISO.

Could be argued that the ISO isn't 'correct' if important highlights are blown. Then the 'correct' ISO would be a lower ISO where the highlights are protected.
