ᐅ Wooden Fence – Significant Color Variation

Hello everyone,
I would like to ask for your opinion and expertise.
We ordered a fence that looks quite different in the catalog compared to the actual product delivered. It is made of pressure-treated wood. According to the supplier, the fence’s color will change over time towards the desired shade. They say that the dark color right after treatment is a sign of quality.

However, the current color does not meet our expectations at all.
Attached are some photos. Does anyone know if the fence will realistically look like the one in the catalog (and shown at another supplier as well) anytime soon?
We are unsure whether we should exchange the fence.

If an exchange is necessary, I would be interested to know if you are aware of wood types that do not typically have such color variations.

Without realizing it, I consider that very unlikely.
Natural larch, oiled for example, would be light and durable.

Catalog (image editing) versus real! It is always a color dilemma. Always check in real life.

The photo looks like natural/larch clear,
the delivery appears to be color treated.
Check the label attached to the pallet or take a photo of the label.
Best regards, Nida35a

Many thanks to you all for the answers.
For your information: we have seen the fence in person (see attachment). According to the supplier, the dark color is due to the pressure impregnation treatment.
I have also attached the pallet label.

Well, it clearly says color tone "brown" .. nothing to do with boiler or other stuff.
