Wet Infusion or Prepreg?

I had these parts made for a project I am working on and the manufacturer claims they are 'autoclave dry carbon', which should mean pre-preg, but to my untrained eye it looks like regular vacuum bagged wet infusion. There are tiny bubbles along the edges and the outer clear resin layer seems thicker than what I would expect a pre-preg.

Are there any carbon experts out there that can help me identify what process they used to make these parts?

On eBay I’ve seen many carbon parts where the pattern on carbon, whether going left or right isn’t straight as an arrow. I’d assume this would have to be infusion?

Parts made in Chinese factories just aren't good quality in general, more likely to be the result of a hurried layup than a result of the process. 

Of course complex parts with extreme geometry will test both the skills of the laminator as well as the material conformability, however the parts the OP posted are very straight forward and I would expect a straight weave even with wet-laid parts.
