The reason I am asking because normally the car sits weeks/months at port and in dealership's warehouse. Those disk rotors are very prone to rust, isn't it?
I know I am noob and I want to enrich myself from your experience :-)

Yes. Rotors will rust literally within MINUTES of getting wet. They are cast iron. It is completely normal, and will wear off after a few minutes of driving. They can even rust so quickly that it can take a bit of engine power to "unlock" the pads from the rotors the next morning if you parked the car after having driven in the rain.
