The only downside to the Note 4's panel is its gamma value of 1.97, which is below the reference value of 2.2 – the iPhone 6 Plus is close to perfect, at 2.18. In practice, this means that the Note 4 delivers a punchier, more contrasty image than it should, though the effect is not so overdone as to be annoying or distracting.
Average gamma: 1.97
– grayscale errors are minimal.

Conclusion:authors need some more training on display analysis.
Assuming the average gamma is indeed 1.97 and it is not measurement error and/or inadequate measurement methodology.
A gamma that's too low means the response curve is too high, too bright.
A gamma of 1.97 will give a fairly washed out appearance and the appearance of lack of visual contrast and punch to the images.
Gamma at 1.97 is a pretty large deviation: grayscale error can't be minimal.
It also has the exact opposite effect than what describes: "punchier, more contrasty image than it should"
It's nice to have some data, but some appear to be invalid and conclusions are contradicting the data.

Samsung Galaxy Note 4 vs Apple iPhone 6 Plus
Nowhere else does the rivalry between Apple and Samsung cut as close to the bone as with the iPhone 6 Plus and Galaxy Note 4. Encroaching onto true Samsung territory, it’ll be on the 6 Plus to prove itself better than the Note 4, and that will be no small feat given the years of experience that sprung the latter on the scene.
