Calling Sig:
auto [result, red, green, blue, brightness, contrast] = shared_device.gamma_ramp();
Return type:
std::tuple< bool, dcpp::float32_kt, dcpp::float32_kt, dcpp::float32_kt, dcpp::float32_kt, dcpp::float32_kt >
// Can use auto.

Calling Sig:
bool result = shared_device.gamma_ramp( red__, green__, blue__, brightness__, contrast__ );
