Something is weird about this lens profile file. It appears to be for a Canon 85mm lens, not a Samyang 14mm lens, and, as you say, this profile is for JPG files not RAW files. If you want it to apply to raw files you need to change the CameraRawProfile from False to True.
After changing the False to True, because the Make is set to Canon you have to go to the Canon lens list not the Samyang list in the Lens Profile selection dropdown list, or edit the Make to have Samyang..
Because there is an 85 for several focal-length numbers, not 14, I think the correction being applied may be totally wrong. Where did you get this lens profile file? The other profile file you sent has 50mm in some focal-length areas and 85 in others.
To be able to tell if this, or the other profile, is reasonable, you probably need to take a picture of something with a grid of lines, like a brick wall and see if there is barrel or pincushion distortion that is corrected or worsened.
Here is a screencapture of the file as it looks in a text editor with notes about what seems wrong:
