First of all - no, it’s nearly impossible to see that infamous "sparkle" thing on a picture, so don't bother. The same pretty much goes for the overall quality of the screen – don’t bother taking pictures unless you are taking a picture of 2 screens for comparison purposes.
As for 9200 screen, yes, BOTH WUXGA and WXGA+ screen were CRAP, and it has nothing to do with “sparkle”, yes, WUXGA had a lot of sparkle, but its problem was that the screen was crap. WXGA+ was also crap btw. Its just because of the lower resolution it did not shock that bad right away.
As for Samsung/LG – yes, 9200’s LG screen were very bad, Samsungs were a bit better, but still not very good.
Once people start getting their 9300 en masse I suggest we make another thread for those who actually have their 9300, not just guesswork.
As for me – I did return my 9200 with WUXGA and 9200 with WXGA+, both screens were LG and both were just horrendous. I’ve personally observed the infamous Samsungs for the aforementioned models, yes, they were better, but I would’ve returned those as well.
My 9300 arrives tomorrow.
