You may be entirely correct with your prediction and I certainly hope so but….it’s always best to see proof and we should see proof of actual lifespan (in practice) rather than based upon projections by theoretical models….assuming of course LG can meet the challenge of HDR….and I don’t mean the relatively simple capability to support various HDR solutions which marketing executives are touting to thee assembled audience (http://hdguru.com/manufacturers-deba...-ultra-hd-hdr/ ) ; but rather, enabling the LG tvs to produce high enough light output (over something more than a small patch of screen) in order to provide top drawer HDR imagery in the first place, no matter the HDR (open standard vs. proprietary) solution chosen.

Since OLED does produce such a fine picture, in the next 1-2 years we’ll see WOLED (white – OLED) large format panels in some post house(s) for mastering purposes where the monitors are routinely run 10-12 hrs/day. Another thing is that no matter what the lifespan, and this applies to both WOLED and RGB OLED, the current consensus is that running them at high light output (for HDR) will cause them to drift sooner (dictating more frequent re-calibration) than with conventional 100 nit usage.
