If we are talking here about PS3 not passing BTB and WTW for v1.32, then I can say based on my experiment yesterday that yes, PS3 still clips these signals.
On Sony BD's, the easter egg allows you to launch test patterns to check for pluge patterns as well as resolution, display overscan, color settings etc.
When I used the patterns found on UE, I could not see the 3 distinct shades of black under the RED color bar. I was only able to see a dark gray bar and when I turned the brightness on my 70" SXRD all the way up - it washed away.
According to the info. posted here, am I not supposed to see 3 distinct shades of "BLACK" - SuperBlack, Black, and somewhat Black(the bar I could see)???
