SUMMARY
Greetings developers,
Terminal color schemes are commonly being integrated with external (global Dark/Light) color schemes. Often programs running inside the terminal need to be aware of the terminal's color scheme.

EXPECTED RESULT
1. Konsole responds with the CSI ? 997 ; 1 n 	DSR reply to indicate dark mode or CSI ? 997 ; 2 n 	DSR reply to indicate light mode
