mine is a dual ips setting with a rather disappointing 'warm' color calibration to them. i bought it 2nd-hand. it's a LL unit but identified as US (XL) machine (CFW). it's my first 3ds ever and it plays great, no complains. that is until i saw other 3ds-es and began to suspect that my screen is not as bright as all of them. I had to confirm my suspicion and went to a local game store to compare my unit. did the comparison with several old 3ds xl (all they have is the old version) and true enough, my dual ips new 3ds ll/xl at full brightness setting is dimmer.
at 1/5 : nearly identical brightness
at 2/5 : still hard to spot the difference
at 3/5 : the old xl TN panel starts to shows that white radiation light. but i'd still say they have the same brightness
at 4/5 : this is where the gap starts to widen. the old xl's brightness jumps several steps while my new 3ds ips still doing the same increment as before
at 5/5 : at this point the old xl's can be for some people 'too bright'. my new xl is not even as bright as the old at 4
