[argyllcms] Profiling a device - correct way?

I've been using ArgyllCMS for quite some time now to calibrate and profile my display. But what if I just want to profile it? Since I could not find anything about that specific issue online, I ask here. My usual process looks like this:
1. Use dispcal to calibrate the screen to a certain brightness/gamma and color temperature value 2. targen to create test patches (usually around 400-500, which I think should suffice) 
3. dispread to actually make use of the patches and profile my device
4. profile to create a ICM/ICC-file
But now, I only want to profile a friend's monitor, without calibrating it and messing with the LUT, so that applications know how it displays colors, nothing more. Would that be done just by skipping step one? As I understand, the profile then will contain information about how colors are displayed, but what about 
the gamma value? Would this bring the expected result?

Thanks in advance,

Steffen
