You should always use a correct white balance for the type of lighting you’re shooting in.
If you’re aiming for a warmer look for example, you should still shoot with a correct white balance and than apply one of the warmer LUTs from your package. If you use incorrect white balance for the type of lighting you’re using, you’ll not be able to anticipate LUT’s output.
