Trying to get to grips with APP. Edited a DSLR stacked image, and the saved JPG is less contrasty/saturated than the final edited image showing in APP? 

Here's a screen shot showing the difference. I've output in the various colour space options but it doesn't make a difference.

Any ideas? Thanks.

Yes, this is due to the JPEG compression. JPEGs are 8-bit, APP can process in 16- or even 32-bit. When saving as a JPEG, the color space gets compressed and the algorithm tries to get as close to the original color value as possible, but there will be a difference. Try saving as a TIFF and compare. This will be big, but you can probably see it has more clarity.
