This guy here has posted a review where he claims that the bleed can be reduced by installing the Dell Display Manager application?

Mine's still stating delivery is overdue so not sure when I'll get it. Mulled over cancelling it and getting a 27" 1440p display but I really want 34" 21:9 to replace my dual monitors so will probably see the order through.
I contemplated switching to an AOC 34" but most reviews seem to suggest the flat LG panel is as and possibly more likely to suffer from backlight bleed than the curved version. Plus I, perhaps foolishly judging by some posts on this thread!, feel more comfortable sticking with Dell's support and 3 year warranty than chancing another manufacturer.
What's the general impression of everyone who's bought one so far? Worth sticking with? Is the bleed noticeable in daylight/with the lights or only at night in the dark? I already have a 20" IPS 16:9 display and can't say I've ever noticed any kind of IPS bleed/glow on it unless I view it in the dark using a camera? It looks OK in RL but is similar to some of the above images in the camera photos (especially if you take the photo at an angle rather than pointing straight at the monitor). It's is a lot smaller than a 34" 21:9 though so I can imagine the backlight may well be more noticeable on a larger panel?
