I created a new iok file "PDF size test" (attached) and output PDF from that in vector format, as high quality image and as low quality image using 1280x1024 resolution setting. Then I used GhostScript to reduce size of all three files with the following command:
"C:\Program Files\gs\gs9.05\bin\gswin64.exe" -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=ReducedVector.pdf "Size test Vector.pdf"

[Unfortunately vector and high quality image take 10MB each, so I can't attach them, but the rest of the files are here.]

Now, "Size test Q1.pdf" (1.1MB, Omniscope's low quality image output) distorts the colour in the report. However I would expect it to be more like "ReducedQ10.pdf" (300KB, Omniscope's high quality image output processed by GhostScript). The latter looks perfect on the screen and takes less space.

Omniscope version used: 2.7 b356

Many thanks,
Yuri]]>
