DXO - low contrast areas losing detail

I have been impressed with DXO, but having got over the sharpness and noise benefits, I have now noticed that sometimes it really softens low contrast areas. I have uploaded two images that I hope show what I mean. Look at the green/brown patch in the middle of the frame with the two people strimming.

The first (Capture 1) shows detail and colour variation within the green area, while the second shows a fairly mushy more uniform green for the same area (DXO/Prime noise reduction). I realise its a bit lighter, but if you darken things, it doesn't really bring in the detail.

I have also noticed this in bird pictures, where C1 will bring sharpness and detail into the out of focus parts of the bird, where DXO seems to make it even less sharp and detailed.

I am assuming that DXO is doing something clever, in assuming that low contrast areas are areas where it selectively increase noise reduction. Or it could all be do with my lack of expertise in Post processing. DXO also seems to have added some purple fringing that isn't visible in the C1 image.

Noise and sharpness is still overall better with DXO, but these mushy areas are a bit off putting. It could of course me not fully taking advantage of the controls in DXO.I admit to just using the setting suggested by Tom Stirr.

Has anyone any else noticed this?

Cheers,

Graham
