FandangoNow Picture Settings

I have a TCL 8 Series tv and when watching FandangoNow I’m unable to get into the expert picture settings in the Roku mobile app. Every other app/channel allows it so I can adjust the gamma setting to get rid of the black crush known to this tv. Does anybody know how to get FandangoNow to allow expert picture settings adjustment? That or either add FandangoNow as actual channel? I think the fact it’s not a channel is the issue. Or can we have a developer add gamma to the regular picture settings within the tv?
