I would say the GIMP team does understand that and they often put a high focus on UI improvements on their roadmaps. I suppose they just have limited resources to work with.
I know Blender has a lot of corporate sponsorship, so I think the explanation is there’s a “commoditize your complements” effect going on. But does anyone have a more specific hypothesis? E.g., why does Blender have so many complements and the GIMP so few?
I was under the impression it had more to do with symbiotic relationships between products. E.g., people using Unreal need modeling software (Epic is a sponsor), people using modeling software need GPUs (Nvidia is a sponsor).
I think a redesign of the icons was necessary, because the old ones don't look amazing. But you can make tasteful icons which are also colorful and recognizable.
(And I know you can switch icon themes, but when we're talking about UX, we're largely talking about the out-of-the-box experience. 99.9% of users are going to stick with the default icon pack.)

That said, Photoshop also uses monochrome icons and it can help in some ways to avoid distracting from the image which you are working on. I am not sure what the best compromise would be.
