It is pretty much expected in the darker areas. If you have for instance something dark purple (so Red and Blue have low values, and Green is 0 or close to), and what to make it greener, you have to reduce Red and Blue, that becomes very close to 0, but your Green won't change (if 0) or won't change much (if slightly above 0), so you don't get a dark green but an even darker pixel.
You can avoid this if you use Curves/Levels and work channel by channel, but in that case you may get color shifts where you don't want.
All a matter of compromises, and using the right tools.
Some of the problem comes from using 8-bit images. But you work with high-bit-depth this problem occurs in a more diffuse and less noticeable way.
