Do all current gen. 1GB X55's have screen issues?

Looking around, it seems like ever since the X55 got a new revision (where they downgraded to 1GB ram) people have started complaining about the screen's image quality, mainly in Rocknix due to a lack of gamma settings. These settings shouldn't be necessary ofcourse, since the screen SHOULD be properly calibrated by the manufacturer in the first place. But currently there doesn't seem to be a fix, so it's either run an old JelOS build and compensate for the bad calibration using JelOS' gamma settings, or use Rocknix and have bad image quality.

I have an X55 waiting for shipping, but now I am thinking about cancelling it, since it seems these later revisions are basically faulty.

Are there people that received a 1GB RAM X55 with a good screen?
