Yes. L is quite interesting. A big move with L gets you funny colours too.
You end up having to balance a contrast change in both the L channel and the
"R, G, B" channel to get colour that doesn't go totally wonky.

The clipping is worse, as I would expect, if I use anything above zero for
the white point and black point % setting.
For what it's worth, if I change Media Type from Image to Slide and then go
to Color tab and change Generic to Koday and type to E6, the clipping seems
to be significantly reduced
