This is similar to the hue and cry that came about during the restoration of the Sistine Chapel Ceiling. Centuries of candle smoke and incense had darkened the original colors to a subtle uniformity that had become what people expected to see. When the restoration team revealed the bright, almost "carnival" colors of the original, people were aghast.
I visited the Sistine Chapel post restoration. The colors seemed so bright, gaudy, compared to what I was expecting.
Also, it was small compared to what I thought it would be.
The stairs you go down when you leave are pretty small, too.
