Is RAW image data from the RGB camera accessible in standard SDK?

I am confused about whether RAW image data is available from the RGB camera.

In the example of capturing an image:

public RawImage CaptureImage;
 private void Start()
     RGBCamTexture = new NRRGBCamTexture();
     CaptureImage.texture = RGBCamTexture.GetTexture();

The CaptureImage.texture is type Texture2D which can be stored in the EXR file format by calling the EncodeToEXR() function.

However it remains unclear to me whether the stored EXR image is true RAW image data or it has gone under some image signal processing.

Thanks a lot in advance :).

The image texture you get is the image captured and processed by the algorithm.
