Question Is this a normal level of IPS glow?

The Monitor is a new 1.5 weeks old Benq GW2480 IPS 24" with a LG Display Panel (LG has bad service so skipped them this time).
So is this a normal amount of IPS glow? In photo it looks a bit over exposed. There shouldn't be any backlit bleed as this has no bezels just black paint covering the edge of the front glass/plastic.
Also I have heard that "larger a monitor gets the more difficult it is for the backlit to be more uniform" specially in the case of IPS panels, so is this true?
Also since this is a 60Hz monitor will there be any benefits of using Display port over HDMI?
