So, habe nochmal geschaut und es ist, wie ich es vermutet hatte:

Zitat von dpreview

Even though CA and Distortion compensation will be applied to the JPEG file when shooting in raw+JPEG, the raw file will remain uncompensated. The story is slightly different for Shading compensation which is not only applied to the JPEG but also the raw file. In practice this means that, if the function is activated, Shading compensation will be applied to your output images when converting raw files in Adobe Camera Raw, Sony's IDC or any other raw converter.
