Can't comment on how the color compares to the picture of Spoo, but it looks like that compared to some other fabrics you might know:
Swatches shown are, top left to right, Pale Pink Classic Oxford, Perfect Monday Shirt Blue Royal Oxford, Blue Small Gingham 80/2, bottom left to right, Sky Blue Oxford, Pale Blue End-on-End 100/2, Pale Mauve Stripes Oxford.
I'd not say the End-on-End is a shiny fabric.
I find it a bit tough to compare because they are different weaves, but I would call the Gingham the least shiny, the End-on-End a bit more so, followed by the Classic Oxfords, a bit more obviously so on the solids compared to the stripes, and the Royal Oxford to be the shiniest.
I'd call the End-on-End's blue very similiar to the one of the Sky Blue Oxford.
Still the structure is obivously different as the white is woven into the End-on-End fabric much more subtle than on the Oxford.
Excellent! I love the sky blue oxford, the color is perfect for a oxford. I would also like a bit more formal shirt in approx. the same color, leading me to the end-on-end. Thanks for the help!
