That’s because white balance is primarily determined by how the sensor captures and encodes light, not by whether the codec is RAW. RAW just stores separate metadata—it doesn’t change the original sensor data...
In my testing of various RAW vs All-Intra formats on various cameras, it can be difficult to quickly adjust and match a significant WB issue without RAW controls. Of course it can be done, but WB includes both warm/cool axis and the magenta/green axis. It's an issue of expediency -- with RAW controls it's often a lot faster.
That said, if the camera is white balanced properly, only limited adjustment is needed. BRAW has only been available on the BMPCC series since April 2019, and some of us have shot major work a decade before that. We managed OK without RAW.
The ARRI ALEXA had ProRes recording from the beginning, but I believe it could not record ARRIRAW internally until 2013. Even after that, lots of productions used ProRes 4444. They managed OK without RAW adjustment of WB in post.
On the FX6, I've tested simultaneously-recorded 12-bit ProRes RAW (via Ninja V) and internal 10-bit 4:2:2 XAVC-I many times. In general I don't see much difference, no matter how hard it's pushed in post. There is no significant difference in dynamic range, highlight recovery, or s/n ratio. Starting with Resolve 18.5, there are "RAW Controls for XAVC-I" which mostly eliminates the WB adjustment advantage of ProRes RAW.
XAVC-I in the MXF container also captures much better FX6 metadata than the current implementation of ProRes RAW on Atomos. XAVC-I supports in-camera lens profile corrections, focus breathing compensation, and gyro stabilization data, which ProRes RAW does not support.
My team also uses the Ronin 4D-6k, and we record ProRes RAW on that. One reason is a gimbal is often moving through changing light conditions, doesn't have time to shoot WB calibration shots, and auto WB in post is a hassle. Another reason unique to the R4D is DJI doesn't provide regular 422, rather 422 HQ. At 6k/23.98 that is roughly the same data rate as ProRes RAW, so we may as well shoot that.
But we shot 422 HQ on the R4D before we got the ProRes RAW license, and that was also OK, it was just more work in post.
