Reasonably so. (And thanks for the kind words.)
A Blurb book is not a really fine art book but more like the $25-40 photo books you'd buy at Borders. If you use the HP Indigo profile and sharpen for halftones, color work is very well done. B&W, alas, suffers from metamerism that can vary book to book because their printers' calibration accuracy is all over the place re achieving neutrality. Until they can fix B&W, better to stick to color or add toning yourself.
I had a premium paper book done and did not think it was worth the money. It also makes the color profile for the regular coated paper a little less reliable. I've tried the image wrap cover and did not like the quality of it. Stick to the dust cover jacket if you are printing a hard cover.
Still, hard to argue with the price for having a bound edition of work that is your own.
Nicely done. Were you pleased with the printed book?
