I mentioned this before, the raw - > DNG -> CFR is not using the camera's color matrix, so the comparison is with or without color matrix -- pink highlights relate to the color matrix and white balance. If you prefer to color correct without the color matrix you can do that on RAW2GPCF conversions. In the workspace area of Studio Premium you can select color matrix as "Neutral". If you are using free version of GoPro Studio, click on the "None" preset.
