With the current code you'll have to get your gif image into a
GifFileType.  Then access the Extension Blocks
(GifFileType:SaveImages:ExtensionBlocks) and manually figure out if any
of them are a Graphic Control Extension.  This is because the library
doesn't really do any interpretation of the extension blocks, it just
allows you to access them.  Read=20
http://libungif.sourceforge.net/doc/gif89.txt
page 15 for information about the Graphic Control Extension so you can
write a means to recognize it and use it.

In the future it might be good for the library to know more about
Extension blocks on its own.  But it will take time and developer effort
to work on a brand new version of the libraries....
