Can Displate guarantee the longevity of the paintings?

I think the prices of some LE and ULE can be justified by the fact that they last "indefinitely".

But how can I be sure of this? The painting is made against fading and rust, ok. But do we know exactly what products are used? In particular, I am interested in the impact of humidity on the paintings.

I don't really care about magnets and stickers themselves. Those can be easily replaced.

I ask this because durability is an essential part of the cost-benefit balance. I would not have the same tolerance for a 10-years durable painting than a 100-years durable one.
