Is this normal light bleed for VA panels.

I replace link. I'm sorry I should read forum rules first.
BLB comes mostly from top and bottom, is it due to monitor being curved.
Is curved monitors suffer more BLB?
 
Looking for backlight bleed at high display brightness is rather useless.
With any kind LCD high brightness is only good for destroying black value.
Because that's what it really controls.
It's contrast setting which decides how much brighter white is than black.
Especially when you mention likely darkened or dimly lighted room, you should be aiming for using low brightness.
That also decreases brightness of backlight bleed.

Which is present in some amount in every LCD, even if LCD matrix is perfect, because panel never blocks full 100% of backlight.
And pressure/stress on LCD layer affects to liquid crystals causing variation in their alignment without control voltage and what kind black they do.
Hence highest variation in brightness of black is often near corners.

Curved panels certainly make manufacturing only harder.
Likely causing those symmetrical brighter bleeds in various points of both bottom and top edges.
 
If you're taking the photos relatively close to the monitor and on auto settings of your camera you might not be getting an accurate picture of whether this is a backlighting issue or "off-angle glow" which is normal for any TFT monitor as far as I'm aware.

"If you want to test your own screen for backlight bleed and uniformity problems at any point you need to ensure you have suitable testing conditions. Set the monitor to a sensible day to day brightness level, preferably as close to 120 cd/m2 as you can get it (our tests are once the screen is calibrated to this luminance). Don't just take a photo at the default brightness which is almost always far too high and not a realistic usage condition. You need to take the photo from about 1.5 - 2m back to avoid capturing viewing angle characteristics, especially on IPS-type panels where off-angle glow can come in to play easily. Photos should be taken in a darkened room at a shutter speed which captures what you see reliably and doesn't over-expose the image. A shutter speed of 1/8 second will probably be suitable for this."

Edit:- Also found this interesting to demonstrate the viewing angle effect and that you do need to be further away from your monitor to eliminate this especially on larger screens - http://www.lagom.nl/lcd-test/viewing_angle.php
