Is RAW 4:4:4?

Is RAW 4:4:4, or is the BMPCC still recording in 4:2:2 color space in RAW mode? Thanks!

Or am I making a fool of myself?

raw data isn't even color - it's just black and white (greyscales).
The color comes to existence in the computer, with the dabayering process.

I understand that 4:4:4 color space is better for keying/green screen work than 4:2:2. I was excited for the BMPCC to get the RAW update because I mistakenly thought it would mean the camera would record 4:4:4.
Do you have any idea how RAW recording should impact keying/green screen work as compared to the camera's ProRes mode, if at all, and how it likely compares to 4:4:4 footage for the same, which I understand to be the "holy grail" for such work? Thank you for your time!
