That should be the rendering of the RAW file that LR applies. If you are shooting RAW, the camera LCD + histogram may show you the camera-processed version of the RAW file, which is different from the actual RAW file that you imported into LR, depending on the camera settings. I have switched off in-camera processing, because I could no longer rely on the histogram and LCD.
Go to Develop to process the RAW file. Note that there are standardized "calibrate" settings available on the net that you can use for your camera. Alternatively, you can use 'template' develop settings in LR at the time of import of the raw files.
