I'm not sure I can make this any clearer and I'm not quite sure why you're rehashing points that no one disputes (ie, OLED having deeper blacks than LCD). That was never a question. The question came up when you implied a $6K TV was worth it over a $1500 TV. To be clear:
1. I am limited to 55". The space will fit a larger TV, but the WAF means it won't happen.
2. If I end up buying, my budget is probably NOT limited to the point where I would choose an LCD over an LED for my main TV. I WOULD consider LCD models to replace the TVs in my office and master bedroom, but that isn't something likely to happen for awhile and hopefully when it does happen, the price differential between OLED and LCD will be negligible and the point would be moot.
3. If my only choices were a $6K OLED TV vs. a $1500 LCD, I'd probably buy the LCD for reasons I've previously stated. However, that isn't the case, as at least two OLED models can be had at or below $2,000.
4. As I have also mentioned in this thread several times, if I am buying a new TV tomorrow, I'm getting an OLED and I'd likely get last year's 55" 4K model. I don't upgrade TVs every couple of years - Ideally, I'd like 10 years out of each model and within 10 years, I'm sure 4K will be standard on TVs and most content.
To further illustrate my point, the cost of my plasma repair may be a good chunk of a new LCD TV and yet, I chose the repair option precisely because I value the PQ of my plasma (the G25 was one of the best models of its day) over buying a new LCD.
