Sure, you can lower the Color Temp if you prefer, but trust me that the "yellow" your eyes see will fade very quickly as the eyes will adapt to new temperature (I would say 15-20 min of continuous watching in a dark room). If you are also using other devices with pre-calibrated displays (as iPhones, Surfaces, Galaxy S phones etc.) you would probably also see a temperature close to Warm 2 / W50 (as all are very close to D65 standard), therefore your eyes will be accustomed to watch similar color temp between screens, and you will not notice "yellow" or "blue" tints anymore.
About TruMotion: I noticed that after 5.80.xx firmware, 60hz movies (e.g. all contents from Netflix app) had a slightly worse motion handling compared to before, while 24hz movies (e.g. Blu-Rays) were fine, and this is an indicator that the Real Cinema option (created to improve motion) still works properly there. But on 60hz movies during camera panning (or slow moving objects) a new "ghosting" or judder artifact was noticeable, where objects seemed "double" and almost stuttered when moving.
Enabling TruMotion (but set both De-Judder and De-Blur to 0) fixed this motion issue without any soap opera effect or any other downside, and motion handling on 60hz movies got smooth with no ghosting/stutter again.
Judder or Ghosting during motion does not affect SDR/HDR Game Modes (even with the Real Cinema and TruMotion options disabled and greyed out), as Game profiles are already tweaked to handle contents up to 4K/HDR-DV @ 60fps-60hz smoothly at 21ms input lag without any visible motion artifact at all. And fortunately this has not changed with new firmware.
