Samsung's basic approach is the center of the image should be fairly well focussed. Meaning all three colors should be closely aligned. Going outwards from there the alignment will be worse. The magic number they use is 1/8"... each color should be within 1/8" of the center of a one pixel line. Now if the 1/8" rule covers only the center or the entire screen I don't know.
From having an optical block swapped I think the convergence is mostly determined by the cabinet itself and the large mirror attached to it. The optical block only plays a small part. With this in mind if you want your convergence improved getting a new set is probably your only option.
Working with Samsung is (almost) totally done by your repair guy and at times no fun at all. If possible go back to your dealer as in most cases they will be more than willing to swap sets for you.
I had a screen issue (with multiple back ordered parts) and Samsung made it clear they had no interest in swapping sets. Even their corporate office said such even though my repair guy and two Samsung's service reps said they would if parts were backordered (next to forever).
Magically after x number of calls (more than I could count) I received a call and was given an authorized replacement number. Two days later I had a new set.
The convergence wasn't as good on this set so I had it serviced and while here the repair guy called Samsung and received the above info about convergence. Which pronounced my set to be within specs.
Discussing it with him after the call he took a good look at the center of the screen and decided it wasn't focussed perfectly
so he wanted to swap the optical block. It was his call and I'm sure Samsung would have said it was fine.
Swapping optical blocks I saw a minor improvement although the convergence remained about 90% or more the same. As I posted earlier the real gain was from him doing a manual and electronic focus as I could easily see the image was sharper.
Moral of the story if you aren't happy with your set swap it with your dealer. After 30-days you can still get something done but often it won't be pretty.
