Subtle Changes - Purely for Aesthetics or Lore-Driven?

[LukeyP666]

So since 2.38 hit I was surprised when hunting A-Ranks to find that Marberry had re-rolled and was no longer a Scholar, and had taken up the mantle of the Thaumaturge/Black Mage.

And also when taking on Turn 8 last night, finding that The Avatar had been re-coloured to a darker shade.

I'm sure there are loads more, but these two are the ones that I can think of off the top of my head right now.

Just wondering if changes like this are purely for aesthetics or if they have lore-based connotations as well.
