Hi,
I have used IT8 Target by Wolf Faust to create styles which look like the camera jpg processing of my Olympus OM-D EM5 II.
One important thing for me: I used Rec2020 as Input color profile. this way i get much better (natural) color in dark blue. I think standard matrix is “blowing out” extreme colors when you shoot in extreme light conditions (disco, concert…)

(just the last for EM5 II)
Its a good Starting Point for Olympus OM-D cameras (16MP Sensor)
