I'm sorry about that... I decided to investigate after your and Fer15's feedback, because something looked fishy to me, and then I found the bug.Just when I finished testing
On the positive side, I think the APL adjustment works much better now for metric2, and might just work for your IT scenes, too.
You talking metric1 here, right? I've just double checked: The code there is completely different and the same bug can't apply. The code looks alright to me. I don't think there's a bug in this feature. But if you have a good test scene which shows these random reactions, I guess I can have a deeper look.Can you check if there is a bug in the "adjust for brightness" option too? I got randomly low values on dark scenes with it enabled and consistent values with it disabled (same as the bug you fixed for the APL logic).
