While the idea is nice, I think the main issue is going to be that this book came out in 2010, and morph breeding is constantly changing. One of the Amazon reviews from 2015 already mentions that it's out of date, and now we're more than halfway through 2019. The ball python section will certainly be significantly behind current variety and trends; while boa morphs haven't gone quite as nuts, there's still a lot of work that's been done in the last 10 years.
If you're willing to wait until later this year, rumor has it that Vin Russo's revised edition of The Complete Boa Constrictor will be coming out in the fall. From what I've heard from reviews as well as from people on this forum, the original edition already had an impressive collection of full-color photos, and a discussion of localities/morphs with a breeder perspective in mind. In an interview last month, Vin specifically mentioned that the revised edition will include updated sections on taxonomy/genetics as well as an expansion to its picture collection, so it sounds promising for what you're looking for.
