The grid test created to detect image retention issues in Retina MacBook Pros now shows that some Retina iPad Minis have the same problem.

The saame issue exists on the matte 15,6 Display AUR2009 of the ATIV Book 8.
Is that true that there could come one of previously used (refurbished) units as a replacement for my Retina Mini?
And could they tell me they wouldn't replace at all since I have had it engraved?
Is it even legal to run the grid tests? I am worried that if I tell Apple they tell me My warranty is void or something.
