After being turned off for a length of time greater than the Daydream timer the TV will not select the correct colour temperature, Expert 1 after being turned back on.

I have everything connected via a receiver into HDMI 4, and use the Custom picture settings (although the problem effects the other settings too).

Steps to recreate.

1. Set the Daydream timer to 5 minutes (the problem exists no matter where the timer is set too but this allows for easier testing).

2. Set the picture settings too Custom and make sure the colour temperature is set to Expert 1.

3. Turn off the TV

4. Wait for more than 5 minutes.

5. Turn on the TV. 

6. The picture will no longer be using the Expert 1 colour temperature, even though it is still listed as doing so in the settings.

7. Go into the picture settings via the Action Menu.

8. Highlight and click on the Colour Temperature setting.

9. The picture wil revert to using the Expert 1 colour setting.

Does anyone else have this issue? I've tried a factory reset and it hasn't helped.
