@ budafilms remember whether it's 10, 12, 14bit raw it all linear no color space (444,rgb,etc...)
until you normalize it , e.g. full range rgb , rec709 , etc.. .
You should keep with ProRes 4444XQ , The reason why (
short answer)
ProRes4444 , 422HQ , 422 ,422LT are all non liner codec with limited color space (rec709 , 16-235 ,clipping channel's)
mainly for broadcast SD/HD Cams . Where as ProRes 4444XQ is not limited in Dynamic range Full Range (0-255) linear (no clipping)
Read the
Apple_ProRes_White_Paper.pdf it explains it all.

And when you will upload your video into Vimeo or YouTube your video will be again compressed into 8bit 4.1.0.
What are you taking about

4.1.0 ?
The standard for HD & 4K is 4.2.0(web) & SD-DV 4.1.1 (but SD can also be 4.2.0 , 4.4.4 )
4.2.0 color space is the standard for all web video streaming site .
I host my own web video streaming server , from SD 360p to 1080p & UHD/4K (I just compress 4K differently , Band width pig)
I just upload my prores 4444 file after I edited , so recompression is not a issue on YouTube
You know the old statement about data ,"Garbage in - Garbage out"
so the highest quality garbage you can upload (least compressed) give you better garbage out (compressed Vimeo/YouTube streaming file)
