They are technically rather different. shadows&highlights *without* white point adjustment is designed to leave the black point and the white point where they are. This way you keep the overall contrast of the image. This is crucial as otherwise you would keep re-adjusting with other tools like tone curve. Additionally the neutral grey tones are left untouched in the module's default settings - you can control the range of the protected greys with the compression slider.
