Whenever I open an imagem, raw, when loading it has a bright color and when rendered the full preview ir changes.
This is shown with the red athlete picture on video attached.
When a raw file is first displayed in Lightroom the embedded JPEG preview is shown while Lightroom generates a preview of the raw image data. The raw image data will not be affected by all of the in-camera settings. So that is why you see the difference.
This is a common occurrence when the raw interpreter you are using is not the one created by the camera maker.
