How does Spyder 5 compare against i1Display Pro / ColorMunki Display? Spyder 3 was horrible, Spyder 4 was better, but still had problems reading black levels. DataColor states that Spyder 5's black measurement accuracy has improved by some "50%". What is the truth here? It would be nice if someone with i1Pro/i1Pro 2/Klein K-10/JETI 1211 could compare Spyder 5 against i1Display Pro in accuracy. I guess we would need reference-level colorimeter too if we are to compare black level reading accuracy.
