Read the chapter about converters in the customization manual, it describes
how LyX chooses a suitable conversion chain. It is possible that this chain
contains jpeg, that would explain the compression.

No. It is the converter that decides whether to compress or not. If the
default converter from ImageMagick is not doing what you want, add a custom
converter in Edit->Preferences.

Uwe wrote it already: pdflatex likes png, jpeg and pdf. latex likes eps and
ps. Everything else must be converted. FAIK this is identical in all TeX

Because LyX converts the image for you if you create the file from LyX. It
does not convert the image if you export the file to .tex (this will be
fixed in 1.4.0).
