The ntsc version requires a tad more tweaking regarding brightness, but i can easily find some settings which are quite pleasing. But i understand what seems maybe trivial to me is not this trivial for users who are still learning some tricks.
If you got some saturation surplus and lack of brightness then you can also raise output gamma np. It works differently compared with gamma correct and maybe you could like it better.
Using masks with strengths lower than 1.0 is also a decent option to gain brightness.
I assembled a sortoff normal ntsc preset with slotmasks:
bloom = "0.800000" bloom_dist = "1.250000" halation = "0.100000" gamma_c = "1.200000" brightboost = "1.250000" brightboost1 = "1.250000" shadowMask = "6.000000" maskstr = "1.000000" mask_layout = "1.000000" slotmask = "1.000000" slotmask1 = "1.000000" slotwidth = "3.000000" double_slot = "2.000000"
Looks like something i can use for gaming without much thoughts. But i also test it on a display set at about 380-400 nits and this can make a huge difference. Display gamma is also important, together with contrast. Assuming that all displays produce very similar results can lead to some sort of missunderstanding. A perfect example for this is the very nice megatron shader where the right display makes all the difference.
