@Paddy, *, Hey that was fun to track down. You were spot on... Looks like a long present issue of JPEGs being exported to PDF were not retaining their JPEG compression. That looks to have changed. Work done by Armin Le Grand on the Apache OpenOffice project and picked up in LibreOffice with commit http://cgit.freedesktop.org/libreoffice/core/commit/?id=8930030323f269a9b3c6bd6a09fc723e09211caa the difference between the two versions are the encoding of the two large JPEGs--on builds through the 4.3.4.1 release the use an uncompressed \FlatDecode, while on the 4.4.0 development builds they now use correct \DCTDecode and retain JPEG compression of original images. Probably will not be back ported to the 4.3 branch, but will be present when 4.4 is released.
