Shadow correction is not applied to RAW.
Highlight correction affects RAW.
I chose my words carefully.
What HC does is that it underexposes by 1 EV and then push the image up by 1 EV. That is why your minimum ISO becomes 160/200 when you have HC turned on. E.g. correct exposure: 1/60s, f8.0 ISO 80 under HC will be 1/120s f8.0 ISO 80 and then the camera will apply digital sensitivity boost the exposure up 1 stop (and thus ISO is now equivalent to 160).
The effect is the same as if you purposely take all images at -1EV compensation and then push the exposure up in post. So the RAW file is still the RAW file but it is underexposed.
I have HC on all the time (unless I'm taking slow shutter speed landscape) but SC off. Reason: I tend to underexpose to save highlight all the time anyway so why not just try to get correct exposure and let the camera does the highlight saving. SC is does not affect RAW so keep it off.
Taking pictures: RAW (either PEF or DNG is fine) to prevent wasting sensor data
Sharing pictures: JPEG (sRGB, not AdobeRGB color profile)
Editing pictures: TIFF or PSD
Don't bother with anything else.
