Hi rogerio -
If I understand what you're saying correctly, I don't think that's right... unless you mean something different by "split screen" than my interpretation of it.
I set up some split screens
then applied colour adjustments and LUTs to each & there was no issue.
Here are the screen shots:
Colour Adjustment -
LUTs
The one thing I did notice was that (after the split screen was set up), checking Colour Enhancement had NO effect.
