I don't think Tesla can plausibly deny this is a warranty issue, should this ever be tested in litigation or arbitration, as they have replaced many screens under warranty (mine included) prior to changing the policy. Seems to me the replaced screens are, under any reasonable interpretation, an admission that they view this as a defect covered by the warranty. Caveat, I have not read the warranty to see if they reserve the right to change what is and isn't covered at their discretion, but that would seem pretty aggressive.
