Dfine works by making a copy of a pixel layer, so in this case it went above the BG, which it was working on. I could have made a composite layer on top of the curves layers and done it there, and that would be a more general way of using it. This was just a quick attempt to see what detail I might correct in a JPEG, so I wasn't being very rigorous.
Sounds like you're doing things in a good way!
