I think I found a bug in Lightroom CC.... Can you check yours??

Considering you want to Export your RAW file to JPG.. The Original resolution of the image D750) is 6016 x 4016...

If you leave the Export Resize unchecked like this: My exported D750 file resolution will be 2560 X 1709, approx.1.8 MB, this is weird..

If you checked the box and put the Percentage to 100%, your exported file resolution will be as the same original resolution 6016 x 4016, approx. 6.4 MB., which is the way it supposed to be!

2560x1709 suggests that you exported the smart preview while the original image was offline (I get the same smart preview size for D750 photos). Please check the 100% version of the export - I bet the details at 100% are blurry because they are just blown up from 2560x1709.

Nevertheless this is weird behaviour of LR: "No resizing" and "Resize 100%" should result in the same image dimensions - for smart previews it should be the "native" smart preview size, not an artificially blown up size.

It seems that all of the "resize to fit" methods assume the original image dimensions (including the "backwards calculation" from the resolution when you give image dimensions in inch or cm) and will happily blow up smart previews to blurry export images. However, strangely enough the "don't enlarge" option will restrict the image dimentions to the size of the smart previews.

P.S. Independently of this problem, there should be a big warning when some exported photos are not online and are replaced by their smart previews!

Interesting you suggested the 2560 x 1709 is the resolution of the Smart Preview, however, the images are all online at the time and Smart Previews were not made for this library.
