I'm not sure what actions have taken place between your before and after pictures here, but my first suspicion is to double-check the film profile being applied under Camera Calibration to see if that might be causing the discrepancy.
It doesn't matter what profile you use to take the image. With Lightroom, there are default settings that are applied every time you import new images. If you want a flat profile look then you need to modify a newly imported image so that it looks the way you want it to look on import. Then create new camera defaults using those settings.
Lightroom does not read camera-selected profiles. You can choose from different profiles in the Calibration section.
I see, I didn't know this. Thanks for the heads up. I'll try and create a camera default that matches.
