im not sure about that, granted there are not many available and they cost a lot. but based on the reviews of this one things actually dont look so bad

Yep. Considering these are first-generation living room sets (I don't count 11" Sony models, and phones/tablets are tech demos/production tests/etc), there will be some hiccups. Typical for consumer display devices in general, the default settings, combined with some slight manufacturing "issues", leads the colors to be probably slightly over-saturated.
I wouldn't want to buy a first generation OLED display anyhow, because pixel life for each color is different. I think Blue has always been the worst of all OLEDs for lifespan, and green has always been the weakest color in terms of light output. That is... if I am remembering that correctly.
There appears to be an interesting point of comparison between the LG and Samsung:
LG is using a white pixel layer with four sub-pixels per pixel. Three sub-pixels are covered with RGB filters, and the fourth is left uncovered. So, the panel is made entirely of WHITE OLEDs and color is produced using filters. I'll have to dig into the filter design/tech, curious if it's a phosphor approach.
That could help with some areas OLED has been week in, but I have a feeling it leads to color accuracy questions. That white OLED and thus white subpixel also have to be very carefully manufactured, because the color temperature of that white will mean everything. Seeing as it's roughly $10k, I'd hope they have that dialed in correctly, but as things get cheaper I'd be afraid of that trend.
The Samsung, in contrast, goes they typical OLED route - they use the true sub-pixel matrix of Red, Green, and Blue OLEDs.
The biggest concern still, and a quick search reveals nothing for the absolute latest tech: just how long will those OLEDs last, especially the Blue OLEDs? Previously, Blue OLEDs only had a 10-15,000 hour lifespan/MTBF (technically, I'm not sure which - lifespan, or MTBF.. real-world impact is a little different for each word ). If I'm paying $10k for a TV, it's not becoming junk in 15,000 hours. That's weak.
That's a major hurdle for OLED right now. I think the rest, especially color accuracy, gamut, evenness, brightness... those will easily continue to improve with manufacturing stability and diode research... and as long as lifespan and uniformity can be improved/maintained, OLED will easily become THE dominant and best-rated display tech... ever.
It can be out-done with new tech, easily... but OLED is already right on the line of thoroughly outclassing Plasma.
I absolutely love PDP, but, OLED panels are going to easily outshine the best any other display tech has to offer, so long as the rest of the circuity driving the displays remains up to standard. Will refresh rates remain smooth, input lag remain minimal, everyday performance keep up with the best TVs of today? I imagine those 55" OLEDs probably already match the other displays out there - it's just up to the OLED tech itself to mature just a little more.
I cannot wait until OLED is in the price bracket of affordable displays today - because by that time, the picture quality of an OLED set will leave us Plasma owners picking our jaws up off the floor. I alone cannot wait for that pure inky black level. I already am beyond impressed with my PDP's black level, but jesus - OLED will be insanity in comparison. I'm pretty sure OLED black can be measured to absolutely match the best CRT black levels. The whole idea of OLED blacks is, well, zero voltage applied (and no black light), so the only thing that exists is minor light bleed from any surrounding pixels/phosphors. Which is to say, the same as CRT.
