ConTeXt just typesets text, places graphics and runs graphic creation routines which have been grafted in to TeX as libraries.
The only things which should result in pixel information are:
- graphics --- you're in control of their settings when they're created
- internal graphic creation --- at one point in time there were issues w/ transparency, but these were resolved AFAIR
So, check your settings for any graphics you're placing, and for those which you are creating w/in ConTeXt.
Neither of the tools you mentioned are suited for checking pre-press-readiness of a file.
Multivalent has some facilities for validating a file: http://multivalent.sourceforge.net/
as does qpdf: http://qpdf.sourceforge.net/
There are free on-line tools: http://www.pdf-tools.com/pdf/validate-pdfa-online.aspx
Lots of commercial options such as Adobe Acrobat, Enfocus PitStop, http://www.fixmyprintfile.com/, &c. List here:

If you can make a valid PDF/X file, you may find a useful tool here: http://www.pdfxreport.com/doku.php?id=en:faq
