My 55" D series is very close to Rec 709, so at least i have something relative to compare to. That's how I made some decisions. I could adjust the hue and luminance to 0 and get below 3 DE on the 46". It's doesn't help visually at all. I'm also wondering if my Colormunki is off or not getting reliable results anymore. Maybe time to upgrade to an i1PRO w/ a Chroma 5 or C6.
