Follow-up Comment #1, bug #55645 (project octave):

All SVG viewers that I have tested (Firefox, Inkscape, Chromium and rsvgview)
display images pixels antialiased. This tends to make images with few pixels
look blurry as you describe (the most noticeable example is colorbars):

plot (1:10)
colorbar # The image is only 1 pixel wide
print foo.svg
open foo.svg

So this is not really a bug in Octave but rather a deficiency of the SVG
format which does not provide an interface to specify how image elements
should be rendered. 
For example path elements have a property "shape-rendering" (auto |
optimizeSpeed | crispEdges | geometricPrecision | inherit) that serves this
purpose of rendering hint, but image elements don't have such property.

@Muhali: can I close this report as "Won't Fix" since there is nothing Octave
can do about it?
