That's EXACTLY the point.  There is no RFC or standard for "priority".  
  So it should be subservient to all other IMAP flags (including the  
absence of the \seen flag).

  And also, I am able to see the '!'

Of course.  The point being that the \seen status (more correctly, the  
absence of the \Seen flag a/k/a unseen)  -- namely the seen row  
coloring -- is preferred over the priority coloring.  This is by  
design and makes sense from a UI perspective.  "Priority" is kind of  
useless, especially since the vast majority of messages that set this  
flag are Spam; compare this with "unseen", which is always 100%  
accurate.
