But that one (art002e000193~large.jpg) is only 287kB. The Lightroom-processed one is 6.2MB. I would expect original to be heavier.
The Lightroom one was processed from raw. Also, by brightening it a lot, the noisy high-ISO grain becomes more apparent. Noise is famously incompressible, so it leads to a much larger file size.
The resolutions are different, 1920x1280 vs. 5568x3712.
Also possibly different JPEG quality settings.
