Ok, I just did upgrade to GIMP 2.10.2. But I'm not going to upgrade Windows, no way! 
The only 16-bits I have come from Lightroom but I downloaded some sample image from web and it's just the same.
In the link there's a 16-bit TIF from Lightroom, compressed with ZIP algorithm, that I opened in GIMP. Forgive me but I'm still not sure if it can reproduce 16-bit depth.
One thing I know - if I import JPEG to GIMP and then export JPEG, there's vivid banding in sky area. If I import 16-bit TIF, the gentle tonal changes are much smoother. Anyways, I want to know if I'm dealing with 16 bits.
