The topics you want to look up here are color management, color profiles, color calibration, and color temperature. The short version is: setting a display up correctly requires a special device and is too much work and expense for most people not working professionally in a graphics-related field, so chances are good you'll never encounter one that's 100% properly adjusted. In this case, it sounds like your laptop is set to a warmer colour temperature (sometimes called "white point") than your TV.
Personally, I just always use the same screen, whose quirks I know, and make peace with the fact that no one else is guaranteed to see exactly what I do.
