You're correct on the graphics support.
The only graphics in the VT100/VT101/VT102 were the DEC graphics line
drawing set -- if you can call that graphics.

Sorry, but I just don't think this is correct.
VT100 docs (user guide and technical guide, both on bitsavers) do not
mention sixel graphics at all. Paul Shuford's site has some
discussion of what "sixel graphics" means and apparently different
people use the term loosely to describe different things.
The VT125 had ReGIS graphics capability, but this is not a VT100.
The VT220 Programmer Reference Manual also does not mention sixel
graphics, but you can download a font glyph definition and presumably
with the right custom font you could display some sort of image, but
its not "sixel graphics".
The VT320, like the VT200 series, also had user-definable character
sets. You can "fake" some graphics this way like you can with the
VT220. See <http://vt100.net/dec/vt320/soft_characters>.
I know all these DEC terminal models can become confusing, but trust
me, I have been paying attention to which models support graphics.
<http://vt100.net/vt_history> gives these models as supporting
graphics:
VT55: primitive graphics capability
VT105: VT100 + VT55 graphics capability
<http://home.arcor.de/magnos/ccg/vt105/VT105.html>
VT125: Graphics produced as a separate display from the text.
(I am not sure what this means; a separate monitor
required?)
VT240: B&W ReGIS graphics
VT241: Color ReGIS graphics
VT330: B&W ReGIS graphics
VT340: Color ReGIS graphics
