Blackmagic Camera App ProRes 4444 recording

Overall this app looks really awesome, but I am curious about it's ProRes recording.
According to most sources, and a test I did with the normal camera app, my iPhone 13 Pro's highest level of ProRes recording should be only 422 HQ. However, the BMCApp* give me the option for ProRes 4444, so would choosing that option actually capture more camera data, or would it just put 422 HQ footage in a 4444 container?
I'm not sure if it's necessarily a bad thing if it does the latter, I'm assuming it just means it's a bit more of a frivolous option.
*I vote this should be the nickname for the app, I saw someone call it the BMCAMAP earlier in another thread and I physically flinched at how long that acronym is
