After quite a bit of struggle, I got my 2nd sample of the RX1R II that does not suffer from the EVF light leak. It just passed 5000 clicks.
The image review button has become totally unresponsive (DEAD).
Looks like I have to send in my camera for service.
I am not happy as there is no replacement for it while it is gone.
FWIW, I have never had this sort of issues with the original A7 series cameras (or the NEX' before them) at all.
