Default Why still no screen calibration for Nexus 7?

Dear devs,
I have been searching for a way to calibrate our nexus 7 screen since the colours are washed out. I want to know if there is any application similar to nexus 4 display control for our device. I came across ASUS SPLENDID screen calibration app in fonepad 7 device. Can anyone try to port it to our device?
