From your screen shots, I feel that OM1 has better dr than GH7. I use art filter 1, which is a high sat high contr filter. On EM5, the dr is too narrow, although I like the color and the contrast, I kind of don't not like the whole pictures. On OM1, it is very usable, I get good contrast, good color, and relative good dr, at least the dr does not distract my eyes.
