For those of you who are satisfied with your EH6000/6001/6003/6050, no need to read the rest of this post as it may ruin the set for you. Maybe not. If you're still evaluating and do not see this issue in these scenes, please report back if possible.
I have two separate UN60EH6050 from Costco and both exhibit the purple/violet ghosting issue. Very minor but it is there and it is consistent with dark edges on light backgrounds. In previous posts, another member used the scene in The Return of the King where Gollum goes nuts with Sam in the swamp as a test scene. When I originally watched this scene, I saw zero ghosting on Gollum's edges. This is because I didn't know what to look for and now that I have seen it, I can detect it in the Gollum scene, but he moves so quickly that it just isn't a very good scene for detecting if your set has this issue. I think the scene right after is much better. Aragorn is silhouetted and walks out onto the balcony. You can see slight purple ghosting on the edges of his silhouette. Another scene that jumps out at me is in X-Men Origins Wolverine near the end right when he gets the top of the reactor just before he fights Deadpool. He's climbing with his claws and then jumps up on the ledge. I can see it plain as day here. During the battle, watch the edges of Victor's coat while they battle Deadpool. All in all the ghosting is minor but it is there on my sets. The Walking Dead episode "Killer Within" shows it as well in the dark scenes in the prison where there's a lot of movement. I think any dark scene with fast moving characters will exhibit the ghosting. The ghosting is not present when you pause the scene or step through it, only when it's playing. I'm wondering if Samsung could at least update the firmware to have the ghosting grey scale if not eliminated altogether.

The purple ghosting issue seems to be isolated to Sharp panels FWIR. And AFAIK
the 60" models only
use sharp panels. So other EH6000/6001/6050/etc owners may not see any symptons of it unless they also have a sharp panel.
Since the problem is likely with the panel itself and not with any software, I wouldn't expect a firmware update to fix anything.

I believe you're right about this, though it seems the 60Hz (Sharp) panels are more affected by this than the 120Hz (Sharp) ones.
There is a workaround solution for this purple/dark-red smearing/ghosting, it's probably caused by the minimum brightness bias-level for the "lcd pixel Response Time Compensation (RTC) / pixel overdrive circuit".
Its overdrive influence the Samsung panels also, happens on my UE40EH6030 with Samsung 40A1AF0D panel, this was discussed somewhere in thread "The *OFFICIAL* 2012 Samsung EH4000/EH5000/EH5300 Owner's Thread"
To get rid of purple smearing:
- set BRIGHTNESS at 45 or above, lower the backlight to compensate the black level.
- set BRIGHTNESS at 50 or above, when LED MOTION PLUS = ON
To get rid of dark/black screen dimming/muting:
- set BRIGHTNESS at 44 or above.
Someone gonna report these to Samsung, so they can fix it with new firmware?
