Well, I noticed the colour change immediately and thought that perhaps the screen was smudged it was that washed out in comparison. I am, unfortunately, reminded of the brilliant screen I used to have as my wife's identical phone has not received the OTA (and we certainly won't be installing it if it comes). Her phone, side by side with mine, simply blows it out of the water. The greens of the battery, reception for example just look, how shall I put it? sickly. Definitely yellower than the other. The "into the nexus" live wallpaper is not as dynamic and vivid as it was before as the contrast has been affected.At a basic level, really not nice. I can see what they mean with certain colours now more visible when the background is dark, but it still doesn't compensate for the overall effect. Couple this to the rest of the bugs which have now plagued my phone with the upgrade (wifi, GPS, compass etc etc) and I would continue to recommend that, unless you had loads of dropped calls or reboots under 2.3.2, it just isn't worth it.
