Yes, we've never had any clients that I know of complain about poor-quality images in our PDFs.

[snip]
As to image quality in PDF, that primarily relates to on-screen display
where the pixel pitch of the original image doesn't match the pixel
pitch on the displaying monitor at a given zoom percentage. If the
number of pixels in the original image differs from the number of pixels
needed to display the image at the current zoom factor, the pixels
need to be resampled, and that process is generally very lossy. When
you print the PDF, the image pixels are mapped to a much higher
number of printer dots, and the image is rendered with all its original
quality intact.
