One of the changes 3.7 to 3.8 was to take the default ambient to 0.0. 
It's a funky color adder disconnected from gamma handling, and at 0.1, 
it tends to brink near blacks way up in intensity with AG 1.0 - washing 
out the contrast in the images. Your 1.7 AG is already compensating for 
this effect to a large degree.

Have you tried changing the default ambient back to 0.1 when changing 
your version to 3.8?
