That is why don't even bother the obvious troll. Salesperson here salesperson there. For all you know, a salesperson has a quota such as to sell the other brands. So they'll try their best to sell those lesser brands in order to get more commission so they'll say anything to get it.
No statistics = no proof.
You want to say it is prone to burn in, yet you do not even own an OLED TV. Look at your phones. Got OLED burn in yet?
Look at this thread. Has there been any user for the past 1 year from the C7's launch that have complained about burn-in? Exactly. As far as I can tell, none. So your words will still remain empty.
OLED is the future. It has happened for the mobile phone market with now the majority of our phone screens made of OLED.
And now the same is applying for TVs with Sony, Philips, Panasonic, Toshiba having also started selling their own version of OLED TV lines.
To add on, for gaming, nothing beats an OLED in terms of latency in the TV shootout. This is because there is no need to power both the panel and backlight in LED TVs which results in higher latency vs an OLED's direct to pixel transmission.
Having the chance to own a slim panel with great visual contrast and still get a boost to power savings is really great for a country like Singapore where we still depend on coal and with the 60% increase in electricity bills where for example, 1kW = $1.60 now and 2kW = $3.20 as opposed to $2 before, I'll say, the pros outweigh the cons which are also not as apparent as you make it out to be.
