[ADV7480] How long does it take for a change to cp_alt_gamma setting to be reflected?

Question

Hi, 
 
 Customer is testing the product by changing the cp_alt_gamma setting value to output a fixed YUV709 from the ADV7480. When changing the ADV7480 register value (converting YUV601 to YUV709 with cp_alt_gamma), how long does it take for the change to be reflected? 
 I'm sorry for the sudden request, but could you please give me an answer by July 29th? 
 
 We believe it will take less than 1 ms. 
 Best regards.

Hi, 
 Run time register configuration doesn't take much time but we can't tell the exact timing how much time it will take. 
 To calculate the exact time, Please add timing api in between these registers . 
 
 Thanks,
