In "ISO Sensitivity and Dynamic Range" table maximum usable range is
8.6EV at ISO 400. Why native ISO 200 delivers less DR?

These measurement softs are sometirmes fooled by how camera deals with lowlight noise and think there's more DR than is there. But ISO 400 and ISO 200 (base iso) are pretty close and difference should be minimal. This is jpeg, so camera underexposes a bit and compensates HL, which could, in principle, increase DR a bit (but with some more noise in shadows).
