Scott Martin of on-sight has published a detailed review of the i1Pro3+:
http://www.on-sight.com/xrite-i1pro3-review/He has been stress testing the i1Pro3+ and i1iO3 table for the better part of a year in a variety of situations. Some questions that are addressed in the review:
1) What print quality differences can I expect to see with profiles made from polarized M3 measurements?
2) What print quality differences can I expect to see with the new transmissive profiling mode?
3) What's different about i1Profiler’s transmissive profiling mode that we haven’t seen before?
4) How consistent will print quality be relative to other measurement modes?
5) How consistent will print quality be if I made some profiles with the i1Pro3+, some with an iSis, and others with an i1Pro2?
There are also some color gamut renderings and discussion about interpreting such renderings. There are some M2 and M3 profiles of the same glossy canvas media that you can download and compare for yourself.
