Awhile ago I ran into a problem with mixdowns and 10-bit outputs.
If you do a mixdown of 10-bit source material and your timeline is NOT set to green-10-bit quality then the mixdown will be truncated to 8-bits, even if your mixdown codec supports 10 bits. It doesn't relate to P vs I. but it sounds like it could be exactly what your CC person is reporting.
I saw this about 1.5 years ago, in version 8.x, wouldn't count on it having been fixed without testing to prove it.

Got a note from CC, bitching that a DnxHD 185x file shows banding on what 'should' be 10 bits input files.
Someone made a DnxHD 185x mix down in a 1080i project, while the content was progressive.CC says that during the mix down stuff was converted from 10 bits to 8 then unconverted to 10.(I know the CC girl who's bitching, she's a total pro, so if what she sees is bad, it is bad. But why?)
Is there any truth in the Avid mistake on downsampling when going from P to I or should I investigate further?(I'm not sure what Avid version did do the output, let alone what has happened in between….)
