This is probably the most accurate depiction I’ve seen so far. It still seems a tad dark compared to reality, but you can see the very slight green leaning that I’m talking about vs your advertising shot above. Not a teal (thank goodness), but just the slightest leaning in that direction.
I expect it to come to life a bit and be brighter in the light. You really do need to see it in person, but many of us who took a chance on it without being able to see it have been pleasantly surprised.
