Hi, when you reset the cinema settings to default ones, the banding goes away? If yes, then a combination of calibration controls is introducing these problems that are not visible at calibration dE charts.
This is the reason I have add over 150 Color Reproduction Patterns
to my Calibration Disk, to help checking the display's controls / various mode settings before calibrating to find their safe working range, detect problems to various setting etc.
Some tweaking of specific controls over some clicks, it's introducing problems because propably are broken and you have to leave them untouched to prevent new problems.
Display Companies are not payng attention to their calibration control systems to keep the production cost low making the calibrating experience more complicated sometimes.
By teaking your controls you can look for smooth color graduations, distortions, discoloration, clipping, banding, posterization, crushed shadow details, raised black levels etc. to find which of them you can touch safely and with what range or which controls to leave them untouched. Sometimes it will require some multiple Saturation points measurements to see if some controls are breaking the linearity of the display to other regions that is not visible by taking simple 6 color gamut measurements.
