Is that the case for all the SVG renderers?
What does "doesn't work" mean, exactly.  Does it signal an error? draw
something with wrong colors? draw complete random noise? just silently
does nothing?  Is the behavior the same for monochrome displays as for
colormapped displays?

I've used 16bit TrueColor displays until quite recently, but can't
remember using (or hearing someone mention the use of) a colormapped
display in the last ... 20 years?  How common is it nowadays?
What else breaks down?
