Short answer: Yes. Early 2013's logic boards are compatible with 2012 displays. 100%.
***The issue there is that the 2013 version further addressed (beyond the 2012 displays version 2.0) the intent to eliminate (not just reduce) the continued frequency of "image ghosting" that customers were experiencing. There was also a shift in percentages represented of LCDs that were LG vs. Samsung (different issue entirely, related I'm guessing to availability and/or strained relationship with Samsung), but that nothing to do with compatibility. If I recall (from a conversation with an apple corp employee friend), they applied an altered version of the coating to the glass face of the LCD (making small changes to improve) that wouldn't affect function. But that's it.
(Jon... I'll address your comments and the implications that go outside the bounds of this question, just a bit... tomorrow when I have a chance). I almost feel like you introduced the idea and need for a glossary of terms manual when discussing all of these repairs (not sure people would read it, since as it is, most people tend to ask questions that have already been answered because it's easier to just post than reading through everything... but it might be useful. Hmmmm
