Comment (by shijan):

 +1 for this. ProRes 4444 and ProRes 4444XQ should render to 12 bit.
 If it helps here are 10 and 12 bit ProRes Test Patterns and ramps
 generated in DaVinci Resolve if it helps somehow to see difference:

 Apply min/max input in Levels and easy see the difference in 10 vs 12 bit
