Hum, I have the Wuben TO10R with XP-G3 (CW, 70 CRI or so) and the Wuben TO46R with XP-G3 (NW, 90 CRI) and both have a major tint shift (towards green).
Only way to fix both was to put some DC-Fix and other kind of diffuser, because even outdoor it was very noticeable that annoying shift (mostly on the TO10R) ! So NW XPL-HI, for example, would be better.

But, to each, its own! About the long presses…if possible, none! But I don’t like long press for ON.
In a urgency, I prefer to have it ready to turn ON!

For this RovyVon, I would prefer not to have the long press; a switch to turn ON and another to change modes would be good, then!
