Notice these are being promoted. Are they a true LED TV, or just LCD

"OLED TV" generally means "every pixel is an LED" - like say a
smartphone.

It may mean that in practice - but there's no fundamental reason why OLED
can't be used as a backlight.

Apart from the manufacturing cost and the fact that OLEDs are not designed
to be long-lived in a constant output scenario, of course ... And yes, I
know that the LED backlights are modulated on some LCD TVs, but the purpose
of the backlight is still overwhelmingly to produce a large quantity of
white light.
