Traces that "look like defects but are not actually defects" in products made with 3D printers are characteristic features that are completely due to the nature of the production method and are a part of the technology.
This is due to the nature of 3D printing, which creates melted plastic (PLA, PETG, etc.) by laying them layer by layer. 
There may be slight variations in colors due to the lights used in the photoshoot.
