"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.

"LED TV" is often gratuitously misused to mean "LED backlit LCD" which
have some advantages as they can modulate the LED backlighting by region
to achieve better contrast, but is not true LED.

It would be equally possible to make a TV using conventional LEDs - as
some display screens do. Technology may allow this for domestic screens
one day - who knows?

Having looked at the LG OLED spec, it's interesting it uses an extra white
LED rather than just RGB, which suggests the colorimetry of the RGB might
not be ideal.
