BTW, the pictures do not look anything like the green blob. Unless it is my computer screen, I am seeing what appears to be concentric circles on the white screen (besides color un-evenness on the other pictures).
The last thing I want to do is turn this thread into one of the manic green-blob free-for-alls that have permeated the RPTV forum for the last year, so I will preface this by saying that these pictures may not indicate any real cause for alarm. This is a very imporant point.
But to counter your point, the "green blob" hysteria in the RPTV forum did not result from sets on which a green blob disspitated a few minutes after warm up. The hysteria resulted from persistent or lingering discolorations. Of course, I freely admit that we do not know how many sets were truly defective, but here I am defining defective as a set that does not exhibit typical warm-up discoloration but rather a persistent, distracting discoloration visible in live picture material. I personally know of multiple people who had to return their XBR 2 and 3 times and still could not get a set that did not exhibit such discoloration. Furthermore, I saw it with my own eyes on several "warmed up" sets at local big-box retailers. Given my own experiences, combined with anecdotal evidence in the RPTV forum, I do not require hard data (which we will never have) regarding the number of defective units to be wary of potential issues.
It is also worth noting that the blobs came in many shapes, sizes and locations. In this case, we have a green discoloration in one corner and a purple discoloration in another. Whether or not this discoloration varies in shape or size from many of those reported elsewhere does not distract from the fact that it does appear to be the same type of discoloration (i.e. a green hue present on the screen in live material). Purple and green are the most common LCOS discolorations due to the nature of the technology, as explained by Dr. Raymond Soneira several months ago, for reasons that place no restrictions upon the size and location of the discolorations.
