In our saturation sweep, the new Moto X continues to be rather poor in its performance. While on Samsung phones it’s normal to see colors like this on the default display mode, there’s usually a mode that correctly constrains the display to sRGB which is the industry standard for displaying colors. There’s no such mode on the new Moto X, so the display significantly overshoots sRGB. This doesn’t bode well for the ColorChecker, which provides the most thorough look at color accuracy.
As predicted, the new Moto X does poorly in the ColorChecker. There’s really not much that the Moto X can accurately display in sRGB as just by pushing the gamut too far, even if there wasn’t saturation compression for some colors, the large gamut will cause distortion of all colors within the gamut triangle.
Unfortunately, it’s not clear where this lack of attention to color accuracy comes from. In discussions with Andrei it's clearly possible to calibrate the AMOLED panel from the GS4 quite accurately, and there's no real technical limitation for AMOLED to lack good calibration. However, judging by the relatively low peak brightness there are other issues as this could affect Motorola's performance in battery life tests. This seems to suggest that Motorola is unable to access the latest generation of AMOLED panels from Samsung Display.
This would be a rather startling thought, as it means that no matter what Motorola does to improve their implementation of Samsung’s AMOLED displays, they will always be behind the curve. If it becomes clear that Samsung’s AMOLED is the best display from a user-facing standpoint, every other OEM will face significant barriers in competition as they would be unable to access the latest generation AMOLED panels. The real solution here is for other display manufacturers such as LG, JDI, and AUO Optronics to catch up.
At any rate, the display of the new Moto X seems to be relatively poor compared to what we see in the Galaxy S5 LTE-A (and likely the Note 4), along with the iPhone 5s, Nexus 5, and One (M7). While it’s impossible to ignore the power advantage of AMOLED when implementing functions like Moto Display, the relatively low peak brightness and poor color accuracy are concerning.
by the way.
