That paint damage could have been eventually a warranty claim at least on a non exhibition model. As it is not a crash damage or mishandled damage. For the others small concerns it can be easily fixed.
Considering to buy a Rail 9.8, but I am kind of concerned by the battery range.
What kind of average range are you getting from your rides before battery dies ?
Read at least initial question of this thread so you would maybe understand the meaning of that video ;).
Based on the initial question, the video shows that carbon can handle small impact without major damage on frame which same impact could lead to a small dent on alu.
