Case 4 — Disputed observation: is this dial colour shift real or just lighting?

Batch variation on coloured dials does happen in general. Plating, lacquer thickness and supplier changes can all shift tone, so the claim isn't implausible. Plausible isn't the same as confirmed, though. The thread should keep 'possible' and 'shown' as separate statuses rather than letting repetition turn a hypothesis into accepted fact.
