If the bike is assessed correctly and repaired to standard then it should be as good as a factory fresh bike
The trouble is, tossers like 4th dimension want to do it as cheap as possible whilst charging as much as possible, whereas, in my limited experience dealership will create the biggest estimate possible.
My limited experience is from where a car reversed into me, scratch on stanchion where light bar tapped it, scratching the engine bars, bar end and hand guard as it lay down, top box was also possibly damaged (but that didn't rear its head until I arrived at a destination without it!)
Dealer quote was over £2400 on an early 1200 hex, fixed for about 300 all in
Admittedly waay less severe impact to the OP but I believe the theory stands...
