I would describe the carbon vinyl as neither being gloss nor matte. Real carbonfibre on road cars (not F1) usually has thick lacquer and that's what emphasises the visual depth. The carbon vinyl is excellent as a decorative finish and is carbonesque but no way does it look like the real thing except possibly to someone who has never seen the real thing. It has a plasticky sheen and that satin sheen is very typically vinyl.
In photographs it can look closer to real carbon due to lighting but not in real life.
So, if you are going to have carbon vinyl, don't fool yourself into thinking that others will think you've got real carbonfibre components - It's just a wonderful decorative finish.
