the shielding would be copper tape (the better option) or paint that is in the cavity. Sometimes the paint is done half arsed, so it doesn't help much.

the proper shield setup is the copper tape in the cavity and back of the pickguard, also same tape in the cavity of the output jack and back of the plate.

and then a wire is soldered to the tape some where, and attached to the ground wire from the output jack.

If that has not been done, I would not consider the internals properly shielded.

I can't say with out doubt, but I can be pretty confident this would NOT be done by the factory.

Factory shielding is carbon paint in the cavities, sometimes over-sprayed by the top color coat, but there will often be black visible around the part number bar code stickers. There will also be a ground lug just forward of the volume pot.
The pickguard will usually only be shielded in the control cavity area, with silver foil tape.
I've not seen copper tape used on common production guitars, and rarely (never on Fender) seen tape used in the body cavities.

I've never seen the jack plate cavity shielded... but the extra wire is redundant. If the shielding is done using tape, then a narrow fold of tape over the top of the body at the screw holes makes positive contact to the ground.
Likewise, wrapping the tape onto the surface of the body makes contact with the pickguard shielding, which is in turn in contact with the pots... *however*... relying on the stem of the pots is not reliable in the long run. Just a few days ago, someone posted a CBS-era Strat that had ineffective tone control. We never saw a resolution, but there were no ground jumpers from the volume pot to the tone pots from the factory... CBS relied on the foil to provide the tone ground!
So yes... you do want to install a ground lug into the body in contact with the foil (no need to solder to the foil directly, try not to make things reversible, you will some day need to remove the plate and electronics).

Guaranteed the most that was done was what I described in the first paragraph... and if that was done, it is as effective as anything we can do to "improve" it.

I agree with the above comments that it is the owner is maybe due to using a new pedal that bumped the gain, or it is coming from something in the room like a computer or cellphone.
With the noise being present with the volume turned down, I can guarantee that it's NOT coming from the guitar itself unless the wiring has broken, because when the volume is turned down, the output jack is shorted to ground. The only noise coming from the amp is from the pedals, amp, or cable... the guitar is removed from the circuit.
