No. The pdf format can handle both vector and bitmap images, allowing
for compression in the latter which provides one of its advantages over
postscript (another being the ability to embed and subset fonts,
another being DRM-style features &c &c).

The output of Quartz is, by definition, a bitmap image since it's being
sent to monitor pixels or printer dots, so when screenshots are taken
only this data is being used -- Quartz was simply not designed to
output vector images after the composition stage.

This is true. You would not want to convert eps to jpg or png. However,
any eps file may be losslessly converted to pdf, provided font
availability (much of which ghostscript provides).
