Display iMac Late 2009 color profile questions:

My friend dropped his mid 2010 iMac 21.5 inch desktop computer over for me update to Yosemite because I have a very fast connection.

I have a late 2009 iMac 21.5 inch.

When side by side, I noticed that my display is quite dim compared to his. Also, the "white" seems dull and grey/yellow. ( I shot this photo with my iPod Touch of the displays side by side.)

Both displays are set at the highest brightness.

I took note of the color profiles of each.

My question is this: Can I make my display look somewhat brighter? Or is it different because of something else? His iMac is so much brighter. I'd like to brighten things up on mine if possible.

Below, please click the image- on the left is the 2010 iMac, on the right, the 2009.

the 2010 iMac says 21.5 inch (1920x1080) ATI Radeon HD 4670

the 2009 iMac says 21.5 inch (1920x1080) NVIDIA GeForce 9400

Something tells me that I can't calibrate it to look like that, but, I figured I'd toss the question out there. I had no idea how yellow/grey my display looked until today.
