The image on Camera Raw does not match to the one pocessed

[mtakeda]

I send the file to PS and then sometimes I do process them somewhere such as the curves, hsl and other portion of PS first then come back to Camera Raw. But the problem I face is that the Processed  image ( back ground layer) and the image shown in the Camera Raw window are different. The latter tends to be lighter and less saturated. Can anybody help? Thank you.

It comes back to Camera RAW? So you are opening the file as a Smart Object so you can go back to ACR? You eventually have to open it to export it so I'm missing something in your explanation. Are talking about a file in LR you send to PS?
