Patina on Superluminova Models? (2012+)

Bought a 2223.80 last year, already had this cream-colored tint on the lume but I thought nothing of it due to inexperience at the time. Looking around after at other examples, especially on YouTube and online, I'm finding that the lume is supposed to look closer to white under the brightest lighting conditions, and mint in darker/warmer lighting.

On the other hand, mine looks mint under the brightest light, and in indoor light, it's almost the same color you'd see on patina'd Goldeneye examples.

I'm curious if anyone has anything to say about this, wondering if I got a crappy model. I don't think it's a UV exposure issue given how the bezel maintained original color...
