UV absolutely does fuck Lego but part of what you might be seeing is actual color difference, the old light and dark grey colors were warmer and a little yellow or rustic colored, while the new ones are more of a flat light grey and a VERY obviously cool-tinted dark grey (leading to people calling the new greys blue-grey, or bley, as in 'dark bley looks like Mega Blox, i hate it').
