Had this TV For a week now after thinking my panasonic 4k was bad! I'm wondering does anyone have the same issues as me?

Delay turning TV on and off.
Lag in menus
Lag in picture & sound
Lag in motion
Difficult to connect to IOS.
No WWE network app? Does anyone one know when it's coming!
Finally and most annoyingly when watching fast Panning action IE football the grass has a smudge effect when the camera pans!!

Any help would be appreciated especially with best picture settings for Football.
