OK so having looked up garage band mixer..........
In summary, you can find the mixer functions within the track settings in the Tracks area, allowing you to control various aspects of your mix, including volume, panning, solo/mute, and effects.
so what else has your guitar got added to it in garage band - if anything? that might be the answer. as above 'ambience' in garage band is a mix of delay and reverb. 'vocal ambience' might well have eq, can you read out' the settings of the ambinece preset ad match them in your kemper?
(You are using the kemper in church aren't you and not sending your guitar dfirect to the mixer?)

And having looked up the Kemper user manual you do have a phones output. you also have speaker cabinet choices and a whole arrray of eq and reverb settings. You really should be able to set up the sound you want so it sounds good in the headphones at home direct from the kemper and not through garage band.. then save the patch as i suggested above and that will be the sound you are sending to the mixer in church.

I can't for the life of me understand why you can't achieve the sound you want without looking for an outside solution. i don't believe garage band can add anything the kemper can't. you might need to experiment but it must be possible. are your headphones at home the same as those you use for your in ear mix? are the home phones wired and the in ear mix over wireless? is the sound guy eq-ing your sound to what e wants and not what you want and then sending you the master mix? as mentioned above we are missing a lot of information.

what the sound guy sends out to the front is someting you can't control unless you can hear it. have you tried using a long lead and listening from the front during a practice session?
