Reasons to use RAW over best quality JPEG

The ice on the water looks bluish because it is reflecting the colour of the sky. The colour you show is technically correct but in real life, our eyes adjust and we think we are seeing white. So, your camera has captured the colour correctly but it will be up to you to tone down the blueness.

Your example therefore shows a good reason to use raw. The colour correction can only be properly done in raw - any attempt to change the colour in a jpeg will impact the overall quality of the pix because you have much less data to manipulate - your efforts wiould be like a broad brush stroke versus a fine brush stroke.
