No, but having just been in Siena itself for 3 weeks I don't feel too deprived! Although I WILL go see it when it gets to London as there are some things (and parts of things) in it I've not seen yet.
I won't be able to get up there for this one, but I am grateful for their 4K exhibition tour on You Tube. The colors look amazing on an OLED screen. www.youtube.com/watch?v=0DUi...
