24" brightness gradient, color shift, or both?

Question

We all know about the "issue". We've all seen the pictures and seen them in stores. However, I think I'm a little confused. We talk about some machines having a brightness difference and a blue/yellow tint.
Which one was the most concerning problem? Is it the brightness difference everyone is upset over (like this: http://forums.dpreview.com/forums/read.asp?forum=1017&message=27915616), or is it the slightly bluer left portion of the screen (setting a grey background and seeing the difference on the left side or seeing a yellower patch in the middle)? Or, are these problems one in the same?
In my case, the brightness is even on each side, except the left side does have the ever-so-slight bluer tint to it on about 1/3 from the left (you can be picky and maybe detect a slightly brighter left side too on a couple pics, but then again, so does my buddy's ACD at work).
I'm mostly for keeping mine, but to be honest, want to see if these issues are separate or considered one issue (the more brightness difference, the more yellowing, etc). The issues don't bother me during normal use and have to look for them to see them.
BTW, I took a boat-load of pictures here: http://public.ryanpetersonline.com/imac/
So are these two separate issues? Thanks.

Yes, the 2405FPW uses a PVA panel (Samsung LTM240M1-L01), but these
are certainly no more expensive than S-IPS panels used in 24" iMacs. Much
of the Dell's high price tag was due to the numerous deluxe features having
nothing to do with the LCD panel (multiple inputs, universal USB memory
card readers, 5-year warranty, etc.) Pretty good value compared to a 23"
S-IPS Cinema Display -- $1000 (including AppleCare) for ONE video input
and exactly ZERO features.
BTW, the current 24" Dell 2408WFP sells for $620 -- with an S-PVA panel
(Samsung LTM240CS05) and all the bells and whistles of the 2405 -- PLUS
HDMI, HDCP, and 110% color gamut. The ACD is a vastly overpriced fossil.
My main goal of this thread is to see if this type of mild color shift can happen
in LCD's other than the imac's. Perhaps the brightness of the machine brings it
out more than usual.
I've never seen a noticable color shift or brightness gradient in ANY of the
dozens of LCDs I've worked with. Pure speculation, but I wouldn't be at all
surprised if the problem is somehow related to Apple's irrational fetish for
"slim" profiles. Betcha a nickel Apple leaned hard on LG.Philips to invent a
thinner backlight/diffuser/inverter assembly. ...consequences be damned.
