The thing is that SAMOLED is far more natural to your eyes. LCD shines backlight right in your face, light that comes through a thin layer of colored "crystals" and that's how you see the final image. That's why they seem more washed out, and I suppose that's what you're used to and that's why amoled appeared strange to you.
So LCD is like break lights in your car - it's white light shining through a red material, so it appears red to you in the end, but the light is not really red.
Amoled is more like looking directly at a source of red light. The "red" there is really more red.
LCDs have huge amounts of flaws that are actually bad for your eyes - low contrast, poor viewing angles and blurry motion are the biggest issues, and they are almost nonexistent in AMOLEDs.
Amoled screens actually consist of pixels that display the image by themselves, without a backlight behind so the image appear totally different, more realistic, much more vivid - simply because they can display whatever color you want them to display by themselves. So there's no limitation to viewing angles or contrast, or real color vividness. So they appear more "in your face" but that's because they're more natural like that.
Samsung's Amoleds appear a bit oversaturated to some people, especially die-hard LCD users.
