I noticed image retention once yesterday when I was shutting down, I could see a faint image of my desktop background. I just performed the test posted earlier in this forum and my screen passed so I'm not sure what to think at this point.

I say enjoy it for as long as you can while it is problem free. If problems do arise, then have Apple look at it.
Personally, I feel like I've wasted a bit too much time worrying about a something that could potentially be disastrous instead of better using that time to just soak in the experience that is available now. Going forward, I'm doing a 180 on my original doubts and worries. For all we know, a silent revision has already taken place, or there may be one impending.

Thank you for the refreshing postI say enjoy it for as long as you can while it is problem free. If problems do arise, then have Apple look at it.

Very good advice, it applies to MacBooks screens and Life!
I don't think that's retention if I'm right about what you're referring to. The screen goes white-pale before shutdown, made me think of retention too but it happened to my MBA.
Try the checker test.
Guess you got a 13". None of us know either. Welcome to blissful ignorance!
Yes a 13inch.
Can't wait to see when someone finds out. Calling apple would they be able to tell me which one I have with my SN? Is this a legal obligation for them to present us that information?

QNIX make great displays
Late-2013 Haswell rMBP13 /8/512
Manufacturer: 0610 (as everyone)
Model: A018
Manuf. date: CCD71000
Unfortunately there was a small bump in the bottom case, so I called Apple to mention it (to prevent denied warranty in the future), but they ended up sending me a replacement machine :/
FWIW the screen was fine after marco.org 10 minute checkerboard test (remember to look away to persistence of vision problems)

Sadly, I suspect we are all LG panel owners - as far as I know, 13" are only LG.
Source?
These are the 3 13.3" retina panels I've been able to find - both Samsung and LG:
LSN133DL01-V07 SAMSUNG 13.3"
LSN133DL01-V01 SAMSUNG 13.3"
LP133WQ1-SJA1 LG Display
see my link:
http://www.panelook.com/sizmodlist.php?order=panel_id&by=desc&sizes[]=13.3&panel_type=a-TFT&resolution_pixels=25601600&production_state=1
I know you're going to get a new laptop, but can you run the command mentioned in this post? It will give an exact production week and year.
Only the LG one is IPS in that list, the Samsungs are PLS. Not sure if that matters though.
For all intents and purposes, they are the same:
http://en.wikipedia.org/wiki/IPS_panel#Super_PLS
>> ioreg -l | grep IODisplayEDID | sed 's/^.*<//g' | cut -b 33-36
Returns: 3016
More info:
My Spyder3Pro using Argyll (./spotread) shows that the centre-luminance is 310nits (270nits top left corner).
Here is my sub-pixel layout.

These guys have an mid-2012 retina review, and they refer to the Samsung PLS panel:
http://www.digitalversus.com/laptop/apple-15-macbook-pro-with-retina-display-2012-p13532/sneak-peek-macbook-pro-next-gen-retina-display-n24927.html
"Like with the new iPad, Apple went with PLS technology (a derivative of Samsung's IPS displays). " [for the retina MBP15]
Same sub-pixel layout as mine
Therefore I think that the A018 screens are Samsung - *assuming* that digitalversus is correct with having a PLS type panel.

Out of curiosity, how did you photograph that? DSLR and a macro lens?

Well, my haswell 13'' is A018, and it displayed image retention. So if it is a samsung, looks like samsungs can have IR too.
Either way, its going back. 13'' was a bit too small for me anyways.
I have a Nikon SMZ645 stereomicroscope in my home lab
x50 magnification. I found it easiest to take the shot with my HTC One S through the eye-piece (it was really hard to get a good picture, because I had to hand-hold)

Your IR on the A018 was after 20mins. I would consider that "not unexpected" (if it is tolerable is a different issue, but it is widely know:

Nice
Not everyone has one of those, though. I should see if I can get a hold of a macro lens and attempt something similar. I got somewhat close with a 70-200mm at 200mm but I had to stand back a few feet.

That is not image retention. It is a Mavericks bug. There's a thread about that.

Correct.
I have it on my Mid 2012 rMBP [ Samsung screen ] ; 2013 MBA [ Samsung screen again.. ] and this late 2013 rMBP I got yesterday [ LG SJE1 screen ]
