YES. PLEASE ADD THIS!
I can currently do "free" or non-DRM content using Hue Sync from a PC but it would be a HUGE feature to add this natively to WebOS. Application needs to send information about the displayed colors on a given area of the screen to the Hue Bridge over WiFi link. Hue Bridge would then tell the Hue Lights how and when to change color values.
As there is no way to output video from the TV, the content providers should not have any DRM concerns. This would be the absolute cleanest solution and at least in the US market and would funnel so many buyers towards LG units.
Summary of wish:
Feature to be added to the "all settings" menu somewhere under display
Selection enables the TV to run Hue Sync software
TV then connects to the Hue Bridge on customer premises
Whatever content is displayed on the TV screen from whatever source (streaming, cable box, etc.) is analyzed by Hue Sync software for color/placement information
TV sends color and screen area information in real time to Hue Bridge
Hue Bridge tells Hue Lights the appropriate color adjustments to make
