Pink Tint and Brightness. topic

Hey guys, just got my nexus 6 yesterday and I noticed I have the pink tint issue only when I'm using adaptive brightness, its not a big deal for me but once kernels get gamma control support would we be able to fix this issue? just curious if its fully a hardware problem or software.

Also I don't if this has been answered already but why does the brightness go so much lower when adaptive brightness is on?

Any insight would be great, thanks!
