mixing binlog formats between master and slave
It might be in the manual:


  Each MySQL Server can set its own and only its own binary logging
  format (true whether binlog_format is set with global or session
  scope). This means that changing the logging format on a replication
  master does not cause a slave to change its logging format to match.
  (When using STATEMENT mode, the binlog_format system variable is not
  replicated; when using MIXED or ROW logging mode, it is replicated but
  is ignored by the slave.)

That is "Yes" to your questions.

Note that ROW is the default for 5.7.  That is, ROW has proven itself to be the 'right' way to do replication.  Galera clustering can't even work without ROW.
