The lifespan of rgb OLED material has currently been extended to 45K hours to half life. That translates to a lifetime of over 10 years if a television were viewed 12 hours a day. Prototype green OLED has been extended to 198K hours to half life and blue 68K hours to half life.
As previously mentioned, LG uses white OLED with rgb filters. That should eliminate the low efficiency of others OLED colors, which is now almost a moot point. I have not found specific data on the life of LG's white OLED material.
The main problem now being worked on is how to improve the brightness of OLED to allow OLED to display HDR (high dynamic range) for the new 4K spec. Currently LCD still excels in brightness because it is non-emissive and the LED backlighting can be driven to higher levels. OLED is emissive and creates its own light without the need for backlighting. An individual OLED pixel can be turned on and off 100% allowing "infinite" contrast.
