I asked off-list about others' experience with the issue. Here's the response from Kevin Wheatley of Cinesite: " nuke does not support the chromaticity attributes at all and strips them out on reading and has no support for writing them.
Just like most apps don't. " If you can configure RV to ignore the primaries in the file, that is probably your best bet.
