If you're in love with your Note 4, don't install the following app. But if you the type of person that wants to know everything, is curious, and doesn't mind fiddling around with the hardware on Note 4, you're welcome to install the following app, and share your feedback,
Install supercurio's Voodoo Screen Test Patterns App,

Bring the Brightness level down to minimum visible brightness (Preferably when viewing Near Grayscale); even in a well-lit room, or preferably dark setting, you will notice how Samsung managed to hide the Mura Effect on their latest iteration of AMOLED Panels. Some will see notice the predisposing lines, blobs, banding, and two-tone (or even more) gradients, which expresses the true organic nature of AMOLED Panels (Discussed as far back as the original Galaxy S phone).
Now beware, the Mura Effect is normal and does not make your screen or device defective.
Thanks to Samsung's preset for low Brightness levels implemented on the Galaxy S4, S5, Note3, and Note 4, and newer devices (can only be modified via third-party apps), its really hard to make out the Mura Effect on the newer models. Black color is Black, and Samsung's software mod forces no voltage to be fed to the AMOLED Panel when black is displayed, thus the pixels are literally turned off.
I've seen some users post pictures of the smearing (deep purple and pink tint) at "Normal" lower brightness levels (within Samsung's preset levels), which should be taken into account; I suggest them to exchange their devices or replace their displays until they get something better their eyes can be content with.
Every Note 4 and AMOLED device has these anomalies, however, the degree to which the anomalies are visible will vary from device to device. Some will be unable to make out the anomalies thanks to the nature of their displays (Warmer-toned or Cooler toned displays), and should be grateful and move on. If the anomalies are too obvious, I would suggest replace the screen, or live with it and accept AMOLED at its true best. :D
