Correct. 5psi on a stock tune is limp mode. When in limp the ECU just leaves the N75 wide open so the pressure goes directly to the WG actuator which happens to have a 5psi spring. If the N75 fails this will be the same result.

The stock DV is plastic and not rebuild-able. I don't know that there would be any way to know that it was bad just by looking at it.
FWIW I have a spare DV if you end up needing one. Just PM me your address and I'll drop it in the mail.
