I’m not able to answer the is there a difference question, but you can check this yourself using darktable. @heckflosse gave you a RawTherapee option.
There’s a hidden option that allows you to crop the RAW very early on in the pipeline:
plugins/darkroom/rawprepare/allow_editing_crop
If you set that to TRUE in your darktablerc file you can use the raw black/white point module to crop.
It is off for a reason, I’m sure, but you can use it to do some testing.
