The CM/Toynami version also has the correct finish. A very slight sheen.
Still, I think it's worth waiting to see if HT's finalized retail version will be correct in this regard.
Whoa whoa whoa [this is not my Batman glass ]...
The CM/Toynami version DOES NOT have the correct finish to how the car appeared in either Burton movie. The shine level of it is way too high.
You are right that it had a slight sheen in the first movie.
In Batman Returns, it was blacker, and shinier --
But still not as shiny as the Toynami version is (look at how sharp and defined the reflections in the paint job are compared to the movies) --
The Toynami paint job looks to be based on the repaint done to one of the screen used cars after Batman Returns was filmed. Look at this mirror quality shine on it as it sits in the Petersen Automotive Museum.
You're right, it remains to be seen if HT gets it right, but as long as they turn down the gloss from what Toynami did (but not all the way down to matte of course), they will be closer.
