I just painted some of my trunk/inner fender area with DB164, mine is in Glasurit 68 line paint. when I ordered mine I specified satin finish which is a semi-gloss. I also asked for it to be more matt than shiny and am happy with the finish. As far as I am aware the DB164 only denoted the colour and not the finish but don't quote me on that. I always work on the principle that unless you specify exactly what you want you will always wind up with someones else's interpretation of what you want and its invariably wrong...
If you aren't happy with the finish your paint supplier should be able to add a matting agent to dull it down. I believe you can also alter the finish by altering the thinner ratio but you'd need to check with your supplier.
As far as showing too many flaws then that means your substrate has too many flaws. Paint will only highlight what flaws are there and won't hide them, thats all in the preparation before hand and the cleanliness of your work area. No easy way round that one I'm afraid!
This picture illustrates that, I had just painted this area of trunk floor the day before. I had de-nibbed the primer with 320 grade foam backed paper then vacuumed it, then went over it with panel wipe, and then a tack rag and then painted it, there's still bits of dust in the paint just from atmosphere. This coat was just to get colour in some of the hard to reach areas though so it wasn't critical that it was completely dust free and was done in the workshop and not the spray booth so would have been impossible to get clean anyway.
When it comes time for the final topcoat in there everything will be completely clean, it will be in the paint booth which will also be clean, you could try dampening the floor down as well to keep the dust down. It's all in the preparation.
