I agree with Jeff that you are most likely looking at paint chips. The thing to look for in surface damage is torn fibers. To recap, carbon fiber is made from sheets of carbon fiber that are impregnated with resin. The structure is cured in a mold at high temperature and pressure. You need the fibers to be torn for the structure to be compromised. Damage to the actual fibers looks like the photo below. It was posted to Pinterest by Appleman Bicycles; disclosure, this repairer is local to me and I am acquainted with him personally, but I'm not a customer and this is neither a recommendation nor a dis-recommendation.
The thing with carbon fiber is that damage is often invisible. Many failures are under the surface, and they start from less than obvious impacts like dropping the bike or a collision. Here, I'll depart slightly from Jeff. Detecting sub-surface failures really needs ultrasonic or similar imaging, which requires a competent specialist operator. Those skills are not common, and bike mechanics aren't likely to have them. Appleman and Raoul Luescher, another prominent carbon fiber repair person based in Australia, both got their start in the aerospace industry (Appleman also worked on wind turbine blades). So, you could bring the bike in to the store, but they aren't likely to have better insight than what we can say here.
To be clear: carbon fiber is very strong, and it has extremely long lifespan if handled properly. It is also repairable; with metal frames, a damaged tube would need to be cut out and replaced entirely, whereas with carbon fiber you can repair just the damaged section. It takes more than a little knock to kill a carbon frame. The issue is that it's possible for a knock on the frame to later lead to a failure, and you won't be able to see the damage. So, as with all bikes, you do need to learn how the bike feels and sounds, and you do want to inspect for damage periodically. The chips on the bike are in locations where a failure won't cause a crash, so I would accept this.
As to the wheel, even though it's aluminum, I'd say the same. The damage is cosmetic. Alloy rims can take abuse. That doesn't look to be structural. With aluminum, you would be looking for dents. The scuffed area is hard to dent, but if it did get dented, I would think that watchful waiting would be acceptable. A dent could certainly fail some time down the line, so you would want to keep watch over it.
