Glad to hear you like it on the whole
And yeah it does take a bit of getting use to at first but after a week or so, I imagine that you will find it very hard to go back to 16.9 again.
Regarding calibration etc. unfortunately these 29" models don't get reviewed by any worthwhile sites so you will mostly have to try other peoples settings or/and calibrate by eye to get settings you like, I'm not 100% sure now but settings wise and OSD, it might be similar enough to the other 29" monitors so you can try my settings which are:
- brightness - 10%, personally I wouldn't go any higher than 20% at most (might seem very dull at first but give it a bit of time and it should look great once your eyes adjust not to mention your eyes will thank you in the long run!
)
- contrast - 66
- gamma 1 preset
- colour temp - custom with RGB left at their default values
- high preset for the response time setting, this introduces some inverse ghosting but overall I find it makes a noticeable enough difference to motion clarity
I don't bother with the icc profile for the same reason you listed i.e. too dark and I also have some issues with icc profiles introducing gradient banding.
You can then try to manually fine tune the settings further via:

The white saturation test is great for adjusting your contrast to the correct level.
And just use some calibration images like this:

EDIT:
Cinema/movie preset is quite accurate overall but it was a bit too dark for my liking.
Regarding back light bleed, personally I wouldn't put up with any at all, IPS glow on the other hand is part of IPS but it can be more severe on some panels I find, this is one reason why I use 10% brightness as for me, it pretty much eliminates IPS glow. Supposedly this has improved on both accounts with LG's newer models so that's why I would have gone for the newer/cheaper model I linked earlier on but as per usual, it is entirely up to you.
