Based on article [1], ProRAW is a half way between plain RAW output from sensor and baked in jpeg. It uses computed multiple-frame result, but stores more data, allowing you to recover details from shadows and do other things you typically use RAW for. Debayering is performed (nobody cares about that anyway), multiple frames are combined but higher bit-depth is preserved (12-bit instead of 8-bit), it also contains separate "tone map" which describes HDR gains (for each pixel?). Disclaimer, zero experience with ProRAW, just glanced at that article, but used RAW on DSLR in the past.
