The man page said it cannot show changes to comm, such as when you
use prctl(). In fact, ps can see this. The args field may not change
because its due to the path of the executable but comm can.
The field comm no longer shows defunct for zombie processes, use the
state field for this as it could be obscured if not the last
column anyhow.
