Case 276 — Disputed observation: is this dial colour shift real or just lighting? · reader check exercise

Several posts claim the newer batch of a particular blue-dial model looks more purple than the earlier batch. Others say it's purely photography and white balance. Can we settle this with evidence instead of arguing from different photos?

Review focus: reader check. State what a new reader can and cannot infer from this exercise. Use the original answer fragment “Plating, lacquer thickness and supplier changes can all shift…” as the discussion anchor; no new event or result is supplied.

Exercise RWI-25905/276: address this question within its stated limits.
