confusion about gamma settings

I always see people saying that having a different gamma on different monitors will cause the image to look different.... which makes sense to me.

What I don't understand is how that's possible when you're using photoshop as it's supposed to compensates for all that stuff. If I'm using 5000k and 1.8 on one system, won't the image look the same on another running 6500 and 2.2 when I'm in photoshop? Same thing with working spaces..... doesn't matter what I use (gamma of working space vs. gamma I have set on my monitor) because photoshop compensates, no?

The only thing I can think of is people not using photoshop. If these other programs don't understand profiles, what exactly happens? I thought the icc monitor profiles loaded some curves into the video card LUT so programs that didn't do profiles could still show an accurate image.

Can anyone clear up my confusion?

And speaking of gamma, I downloaded the coloreyes display demo to see what the L* stuff is all about. When I use that, will the resulting gamma be closer to 1.8 or 2.2? I'm just curious what I will see vs. someone who doesn't really have a calibrated display whether they're on a mac or pc. I'm assuming calibrated (and in photoshop) won't matter.

Thanks for the help,
Mark
