Thanks for the comments. I also find the DP3M to be pretty harsh at times for skin texture. That extra microcontrast tends to highlight every crease and beauty mark. I did do some local adjustment in Lightroom to help balance this effect on my wife's skin. This wedding was fun to take some shots with the DP3M because of the Indian outfits we were wearing had a lot of texture and color. I also have some shots with my A7rII and the pictures definitely have a different look.
As far as the saturation/contrast is concerned, I'm curious what browser you are using? On my screen, Chrome and Firefox show the images correctly, while Edge and IE way oversaturate my images. I'm no expert in color management, and I've had trouble getting my images to look the same across all monitors.
