I played around more with my upgraded projector from TVSpecialists.com and I hit my sweet spot for non-HDR 4k material and 1080 DirecTV. Using cinema or reference mode, the settings that came back were slightly less color saturated than I desired so I just tweaked up the color a little and all I can say is wow... Out of the park home run. I don't know how color banding is no longer an issue but I didn't see any where there was before out of certain Netflix and Amazon videos. For example, during the Bosch theme opening (on Amazon) when viewing the sky sequence, there was always terrible banding. Not anymore. I maintain the colors are outstanding. I played a 4k video on YouTube that I had viewed pre-upgrade featuring some colored pencils against a black background, those blacks look amazing to me now.
The demo video on YouTube doesn't really give it justice as compared to actual viewing of the projector in your own environment.
My twin pennies. I will say this, this projector really tasked my learning curve with calibration and image settings getting it to where I am today. From Ronnie's calibration settings to the upgrade, it's been a journey but I am tickled by current performance.
