Well it's defenitly an improvement and it adds to the 1950 a 1960 thema. Which was a very colourfull time to begin with, now a bit more shiny Chrome at a few places and it is near perfect.

Because fallout 4 is recycled fallout 3

Fallout 4, now with 60% more color!

It takes place in a world where it's a nuclear wasteland and people are constantly killing each other for survival. Yet "Just because it's bright and cheery looking with all that sunshine" is what they want visually. Honestly, that sort of stuff doesn't matter to me. I rather them address and reassure people that this game is not gonna be a bug infested wasteland. Nope, they are avoiding that topic like it's like a deathclaw.
