Is this why AP discontinued white Royal Oak 15400?

[Horolojust]

So I came across something extremely surprising and interesting, which is that white 15400s potentially were NOT made with the same dial shade. It’s weird and interesting at the same time.

See the video for details where I show side of side photos of differences and they are indeed noticeable.

The discovery raises a few questions;

1. Are AP doing adequate QC checks commensurate with their price point?
2. Is this was a deliberate change, why did they in their official email to me didn’t know?
3. They agreed that watches from different batches can have slight difference in dial shade. Do we consider this slight and acceptable? I don’t because to me it’s DRAMATICALLY different.
