Have OLED TVs become economic for the off gridder yet?

I was hyped on OLED technology well over a year ago. At that time OLED television sets costs a lot more. At least double. They are much more energy efficient while delivering a superior picture in some respects. 

Anyone have current data on, say ~50" sets?  My 2017 52" LED Vizio TV is a significant user of energy.

    By economic I meant that the energy savings pay for the cost difference. We are not there yet. 55" OLEDs still cost at least $1149 - for a 2018 set. I'll be waiting a few years to see them for ~$500 I'll bet. 
    Here is a 77" model for $5450: https://www.costco.com/LG-77"-Class-(76.7"-Diag.)-4K-Ultra-HD-OLED-TV.product.100488956.html
    Edit - link not working but facts still stand.

    Amazon offers no OLED TVs smaller than 55". Bit odd.

    Can get a 6" OLED "TV":

    *Default resolution is Full HD+ and can be changed to Quad HD+ in Settings.
    *Model and color availability may depend on country or carrier.
    WORLD’S FIRST DYNAMIC OLED SCREEN
    Samsung’s displays have been the in the business for years now and with the Galaxy S10, they’ve taken their game to a whole new level. The display on the S10 is the world’s first dynamic OLED display and also has the first HDR10+ certified panel which means better color accuracy, peak brightness, and contrast ratio. Not only that the display reduces blue light by 42% thereby reducing the damage that our smartphones do to our eyes.

    I was happy when we stopped having to worry about screen burn in and LED backlit screens... Not sure I want a full size TV yet with burning issues:

    https://www.cnet.com/news/oled-screen-burn-in-what-you-need-to-know/

    As lovely as OLED screens are on TVs from LG and Sony, and phones like the Galaxy S9 and the iPhone X, one of the biggest potential problems is burn-in. 

    Burn-in happens when a persistent part of the image on-screen -- navigation buttons on a phone, or a channel logo, news ticker or a scoreboard on a TV, for example -- remains as a ghostly background no matter what else appears on-screen. 

    Last year the screen of Google's Pixel 2 XL phone showed the problem, prompting Google to extend the phone's warrantiesApple's support page for the iPhone X touts that it's been designed to reduce the effects of "OLED 'burn-in'" even as it acknowledges that it can occur in "extreme cases." 

    In the TV world, some owners on YouTubeforums and social media have reported the issue, and the reviews site RTINGS has demonstrated burn-in on LG OLED TVs in long-term tests.

    Ultimately, the dilemma is this: All organic light-emitting diode (OLED) screens can burn-in, and from everything we know, they're more susceptible than standard liquid crystal displays (LCD). But those same OLED screens produce better image quality than LCD.

    I guess I will tolerate OLED in a phone where battery life is very important... But don't want that issue in a TV.

    They have been using OLED  in smartphones for years. They are cheaper and consume less energy. 

    I don't think burn in is a common problem - bordering on theoretical - which of course some folks find a way to get 'er done.

    Curious that 55" is the smallest size though. Very odd. Perhaps that changes soon.

    ?? Huh?  That's been a factor for 80 some odd years - and screen savers have solved it.  Not really an issue any more.

    TVs turned to news programs (ticker/news blurbs at bottom of screen, Logos elsewhere), and such... TVs don't usually use screen savers.

    Normal media viewing--Probably not an issue. However, with closed caption, station logos, freeze frame, DVR, TV DVR, DVDs, etc. that hold an image with "bright elements" on pause for a long period of time--could be an issue?

    If you follow the above link and look through the comments... Burnin does seem to be an issue with some OLED TVs. Closed caption and station/network logos seem to burn in the RED OLED mostly.

    Sams Club had a returned 65" LG OLED for $1200. Pretty tempting. Give it three years or so....it is coming.

    I am a bit confused. 

    From the reading I have done it looks like OLED TV's use significantly more power than LED.  Am I misunderstanding? 

    If that is correct,  why would you want one off grid?

    I have been searching for the absolute lowest power consumption possible. The current contender I a Samsung 32" LED. 

    One habit I have developed lately is leaving the TV on all day for "noise". I need to break that habit before we go on the road.

    I don't know what today's profit maximizers are up to but the history of OLED screens is this: Developed for smartphones due to lower power usage. Wound up costing less to produce after the OLED screens took over. 

    Something odd is up since 55" is the smallest screen size for OLED tv sets. Something odd is up frequently now that we have to do frequent and diligent work on our social credit scores. This is how I massage my numbers (using week-ends assuming that bots are more active and don't out think my clearly superior patriotism)
