disable GSR & TPC

Hey!

I was able to connect my LG C5 with ColorControl and clicked on disable GSR and then did the same for TPC

I didn't see any inmediate response/feedback on my tv so I'm not sure if it did anything

Is there any way to check this?

Also, I am not able to enable the full service menu , can't find the option in the latest version of color control, is this feature gone?
