To understand the difference in the tail lights you need to understand the difference in the technologies.
To break it down simply, think of each LED as a mini light bulb. There is only so much you can do with light bulbs in terms of design and and illumination. For example if you wanted to create the squares of the GTS tail light but with LEDs only, you would need layer of material on top of an arrangement of LEDs to diffuse the light and create the shape you perceive as a square. The square you see in itself does not actually light up on its own. Following so far?
Think of OLED as a display. An OLED has a single organic layer that in itself is the source of light. Therefore it opens up an entire new realm of possibilities. It does not depend on a external source of backlight.
To relate to your example with TVs, LED TVs have LEDs that illuminate and light up the pixels on the scren.
On the other hand, OLED TVs have each pixel also serve as their own source of light.
