Probably because both displays are not calibrated. The LG is also known to have better color saturation than the Samsung display.

Image retention on MacBook Pro Retina

So why is it that everyone wants the Samsung when it has problems too?
I mean LG panels have issues but if they don't. (I can be wrong) but wouldn't LG look better when its first turned on? Compared to a Samsung panel?
Having owned an LG display and swapped for a Samsung, I can say that they both actually look the same.
Samsung is brighter, if anything.
got my LG (IR after 3 months) replaced with a Samsung, after calibrating to my likings... have to say it´s one of if not THE best screen I´ve used...
supersharp and easy on the eyes in the dark <- thats what make a good monitor
Oh yea I keep hearing LG is brighter on this forum...mmm this is something to consider!
I was wondering can you request a Samsung panel when you order online on the apple site for a 15" RMBP?
See I use my laptop about 70% in the dark so this is good to know that it is easy on the eyes.
Be it television or computer monitors I always find LG panels to be brighter when compared to Samsung .....But for whatever reason most of the LG panels I have owned seemed to exhibit technical flaws after a period of time such as IR, dead pixels and even a static/sparkle like pixel interference on 2x plasma tvs I owned!
While slightly duller the Samsung screens are much superior in my opinion and I was ever so glad my rMBP arrived sporting one!

No, but I believe that if your Mac has image retention, you can bring it into Apple and they'll replace the screen with a Samsung panel.
MBPr LG screen is perfect
My LG screen model number is DCN2404031JF49JA5 on MCPr 15"
I have done extensive IR tests and have found no visible IR problems.
I thought some positive LG feedback would be well received!

how long have you had this machine? image retention takes months to show sometimes.
I got it on 17 Dec so not long.
I use my MBPr for 3D modelling, video production, photography and graphics so it's already had a hammering, I have also contacted Apple Business and they have said if it appears they will fix it so no problem if it does appear really!
I have just noticed that the illuminated Apple logo on the back of the screen is a very light pink, in comparison to the white Apple logo on my wife's MacBook Air, could this be the start of Image Retention!?
im no expert but no. completely different "issue" may you call it.. that is just light bleeding through form a different source. nothing to do with the ips display
Red light is weaker than green or blue (less penetrating), so less red can slip through compared to green or blue. Since the pixel density of the Retina display is higher, the effect is even more pronounced. That's why Apple had to increase red light from the backlight unit in order to make the display more uniform.
How do they increase the red light in the backlight? The backlight was supposed to be a uniform white light.. no?

How can you be sure that they do the replacements with only Samsung?
Well, light is actually both a wave and a particle. Or... think of it this way: if you have the right equipment that can "see" the smallest form of a "light", you can actually "count" the amount of each "light color" in a certain light-emitting source.
So all Apple has to do is increase the amount of red light that the backlight emits. It's not that hard to do. You've seen red, green, blue, yellow, etc... LED lights, right? They use the same principle here.
By the way, it appears pink-ish or purple-ish because they don't just need red light. They need some amount of green and blue light as well.
Because I brought my Mac in for a display replacement, and I got a Samsung display back that looks and performs exactly like the LG screen that I had earlier. Just minus image retention.
There is no way to guarantee a replacement will be Samsung. Service parts can be both.
Service parts can be either. And I don't believe I've read any on MR since I got bored of reading the trolling in the IR threads, but I've certainly seen LG service part retina displays myself.
From what I've seen, it's about 2/3 weighted in favour of Samsung, which is the opposite of retail units (which is odd). Since they're probably still new displays (I doubt they can refurb them yet) the service part units will come from the same supply chain as retail devices.
Yes light is a packet of energy called "quanta" or a string of beads called photon.
Given the above, how is Apple manipulating those at the quantum level?
The backlight is usually florescent tubes emitting white light.
Did you mean they have some soft of filter that accentuates the red in the backlight?
I agree that you could get either as part of a repair though i have no idea about the percentages.
I know for certain that you can get either screen as part of a repair. My personal system came with an LG that had IR and apple replaced it with a Samsung screen.
HOWEVER: At work we had a system with a Samsung screen that failed (thin green lines every 1/2 inch or so). Apple replaced that screen with an LG. No IR on it by the way, and the guy that uses the machine was terrified about it and checks it every day for it. That also goes to the idea that NOT ALL LG screens have issues...
Sorry for being a downer but I did exactly what one poster in this thread advised and just enjoyed my rMPB. I've had it a few months now and just the other day I noticed retention similar to the images posted above (most noticeable, the address bar in my browser and spreadsheets being "imprinted" on an empty virtual desktop, together with the LibreOffice button row on top - I have a dark-ish wallpaper).
I guess the most important thing I'd like to know is if anyone has info on whether it can become permanent. Is there any info on this? If "all" it means is that from now on, every now and then I'll have some image retention that goes away after a few minutes but never becomes permanent (keyword: never) I guess I could live with it. Not exactly optimal for 2000+ equipment, though...
But if it does indeed become permanent after a while and I can get my screen replaced with a supposedly less retention-prone Samsung I'd like to do so as soon as possible. We just had the first two official Apple Stores open in my country so guess it's easiest to bring it there for a support chat?
. Ironic eh.
