Not correct. It is not the use of white OLED emission (WOLED) that limits color volume or color gamut, but rather the limited luminance and LGs decision to use a 4th 'white' subpixel to conpensate for that limited output.
If LG used a conventional 3 RGB colored subpixels per pixel, gamut at peak luminamce would increase, but peak white ouput would decrease by ~33%.
If/when LG develops a WOLED technology that can match LCD backlightunits in terms of output, they'll becable to ditch their 4th white subpixel and match LCD in gamut and color volume as well...
abl issue has been improved in the 2017 models compared to previous years. any more improvement would be a good thing.
A trend that is almost certain to continue in 2018 and beyond...
an 'incremental' improvement to peak brightness is kind of a vague term. currently the lg's do about 700-800 nits, incremental could mean they bump it to 900? i'd like to see a 1500 nits oled, this is an area where the oleds have a lot of catching to do with lcd.
We can probably safely assume that 'incremental' means far shy of 'doubling'
Anything less than 10% increase in peak brightness wouldn't even be worth talking about. So my working assumption is that the 2018 WOLEDs will break safely above 1000 lumens peak but are unlikely to achieve 1500...
I think 2019 or '20 could be the year where we see a drastic improvement in oleds. 2018 might be just more small leaps like 2016->2017.
LG has confirmed a two-year 'tick/tock' OLED panel development cycle. 'Tick' years are major changes to WOLED panel technology, 'tock' years are consolidation / small incremental improvement years with little/no changes to underlyng WOLED panel architecture & manufacturing.
2017 was a 'tock' year and 2018 is slated be be a year of much more significant changeto the WOLED panel.
Changing to blue TADF would constitute a major change (as would practically any change to the material composition of the WOLED panel).
Whatever changes are in store for 2018, there are likely to be more hiccups rolling them out than we saw in 2017, and by 2019 we should see those improvements consolidated.
Then in 2020, we're in for another 'tick' year, probably tied to the first 10.5G production from P10 and concievably involving the first printed manufacturing of OLED panels...
