The Apple Prores whitepaper claims that Pr4444: "also offers direct encoding of, and decoding to, both RGB and Y’CBCR pixel formats."

This is confirmed now by many different sources including a guy who can write bit-perfect to Apple ProRes encoder.
Apple paper says encoder/decoder can take RGB data directly (it does internal conversion). Basically that's all what it says in this magic line. Internal data is always YUV (probably for efficiency).
There is no ProRes which stores data as RGB as this is not in Apple spec.
If you want that use DNxHR (just make sure app uses RGB variant for 444) or Cineform.
