I wanted to write "no hardware encoders support full chroma" and "no hardware encoders support RGB" - Wenbin's answer seems to indicate that I was wrong but in any case the qsv code in FFmpeg currently neither allows full-chroma encoding nor RGB encoding. I don't know if mxf (the library used for qsv encoding) support full-chroma and RGB. No idea how your question could be related to post-processing or colour-space transformation.
