Recently I've started noticing the following.

While the car is stationary and keeping it on D with brakes pressed there is more noise coming from the engine compared to when the car is on N. Switching between N - D brings up or down the noise.

Is this normal?

I can't say if it is something new or I just started noticing it recently.

Mine is similar to yours, I guess in D the gearbox still has some load effect maybe the oil dragging? To be honest I don't think about it just drive, however, if the Start/Stop is not functional I do tend to slip into N otherwise leave I leave it in D with the foot brake applied.

I've been aware for a long time that holding the car on the footbrake and then moving to 'N' changes the engine note (it speeds up slightly) and I also feel the car 'relax'. When stopping for more than a second or two I always select 'N' and put the handbrake to 1) avoid dazzling the driver behind and 2) avoid any potential wear and tear (old habits rather than any real knowledge).

Me too

Yes this is normal. In the 6 speed DSG when you engage D it partially engages the clutch since it doesn't matter if the clutch is slipping as it is lubricated/cooled with oil. This provides you with the "creep" when you release the foot brake.

Completely normal and as others mention, I also flick to N when stationary.

I've done over 200k miles with various 2.0TDi's and 6DSG (DQ250) and yes this has been a known "Feature" since introduction in 2003. 

 

Doesn't cause excessive wear and with vehicles with full Auto Hold like the Passat (B6, B7 & B8) and latest Superb the car sits with the DSG clutch at bite point and the car sat with the brakes held every time you stop for as long as you stop. That's how it's designed, the wet clutch has negligible wear in this condition, it's the drag of the clutch lubricant causing the change in engine tone and not direct clutch plate contact with the flywheel.

 

The DQ200 7 speed dry clutch box obviously doesn't do this and the clutch is clear when the vehicle is stationary with foot brake applied. There's always a slight delay before creep is enabled when the foot brake is released. This is why nearly all DQ200 equipped vehicles have hill hold.
