Here, I’m making this comparison by zooming in heavily and using the Objects Level of Detail slider to force different LODs for the Gherkin.
Objects LOD 10 - Less detail, but looks bright and shiny like in real life
Objects LOD 100 - Looks too dark and loses all shininess
Objects LOD 200 - Becomes reflective again, colour is still somewhat off
Only at the highest LOD does the model acquire its proper blueish hue again.
