Sony x900e/9005e - grey balance
After calibrating my tv using Spyder 5 with DataColor's software, I noticed in tests such as AVS HD 709 (white/black/apl clipping), that pure black and pure whites look fine, but some of the flashing bars are tinted blue or red. I've calibrated my monitor (C24FG70) with exactly same settings and all the flashing bars look fine - they are not tinted at all, which leads me to believe that my calibrator works fine.
I don't think the problem is related to tv itself, because when I turn off the icc profile, then flashing bars look grey, as they should (but at the same time, gamma is all wrong and overall color temperature seems way to cold).
It doesn't seem entirely software related because I tried to create profile with DisplayCal - using many different corrections while switching things like drift compensation on and off, which also resulted in tint in greys.
I wonder if it's somehow linked to local dimming - I left it at "medium" during the calibration since I use this value during normal viewing and color characteristics seem to differ with local dimming off, so I doubt that calibration made with local dimming off would be fine for usage with local dimming turned on.
I am honestly at loss here and would really appreciate some help.
