Check,
No, no necessarily.
The FPVs show where the aircraft is going, the PFD where it is pointing.
Flight Path doesn't instantly change with attitude as it has to accelerate to whatever VS the new Attitude/Power combo will command steady state.
With sufficient rate you can have the nose below the horizon before there is any appreciable descent rate and thus descent path shown by the FPV.
It's an extreme example but think of something like Puchakovs Cobra- the attitude all over the shop while the Flight Path is basically stable.
No you CAN'T do that in a 737, but you can have a transitory state in which attitude is temporarily lower than the flight path.
It's all actually a little academic, as the attitude on the PFD is set to an arbitrary datum in any case.
