Remove unused channelIdAndName variable from loop

The line `std::tuple<std::string, std::tuple<bool, std::string>> channelIdAndName;` has been removed from the loop that processes channel display settings. This indicates that the variable `channelIdAndName` is no longer necessary or its usage has been refactored out of this section of the code.
