iMac display acting up.

Sometimes, when I wake it from sleep or boot up in the morning, there is a noticeable yellow tint. This will go away after a while.



Other times, it will start up yellowish and after while go in the complete opposite direction with a slight blue tint.



Most of the time, though, it's perfect.



However, today I noticed there was red patching on the edges of the display that was only noticeable on the linen background of N-Centre & M-Control. After about 20 mins, it was gone and now the screen is looking great. image



So, what I'm asking is - Is there something to worry about here....?
