Some folks do colour pen there seramas, and it is from that breededr that the choc serama's were imported.  I've also read that choc orpingtons (or might have been wyandottes, but pretty sure the former) were imported in the last year or two.
That's good to know. 
I know from Jerry's birds some do have real chocolate seramas, but what I really ment there was, everyone with a brown bird seems to be calling the chocolate now a days with no breeding testing or anything. And we know seramas are a pain to breed to a true color anyway.
The named varieties using hte dun gene are chocolate, khaki and fawn silver duckwing.  I use the term chocolate to describe the darker colour from the dun gene as that is the named variety.  In a genetics discussion, or to clarify. I will usually state somewhere in my post that I am referencing the Dun gene.  When I refer to birds who have the choc gene, I usually call them exactly that.  Not only is "choc" an obvious abbreviation for chocolate, it is also the name of the gene.
It's all part of the "genetics folks weren't asked when the varieties were named" issue.  The reality is that a chocolate coloured bird created with Dun is very similar in appearance to one created with choc.  Quite frankly, I dislike the name "khaki" as that implies a tint of greenish tan, not a taupe tint.  Fawn is a better, and more accurate name in my opinion, although it is a single copy of Dun.
