To your attention, I found settings on Amazon that somebody posted with comment they have payed actually to get them but they will share,
as I was surprised small changes from standard adjustment and what great result by my opinion, all settings before has been adjusted on my set based on Medium white level balance with gamma 2,4 which are still little on colder side, now these simple tweaks below with White balance Warm1 and gamma 2,2 are looking like more universal and for me in previously weak picture result sources/or not that great(on old settings) they were great, dark black details on gamma 2,2 are as have been said of course better, picture is now overally better and not better by small margin
. Pls try maybe you will like them as well. I`m now even more shure what have been stated that too big tweaks without proper profi adjustment are against our visual experience, these small tweaks below show that not big changes can make very big difference, contrast colour richness is very full with these, and more close to what I remember on my old Samsung 2008 samsung plasma(rich colour but not oversaturated) with added benefit of 2014 plasma model which is in most cases better panel.
p.s. I am not fun of Warm 2 settings as it is very dull for me these readjusted settings based on Warm 1 are maybe little bit more off specs like warm2 after measurement but, I definitelly like it like it is
(missing colour of Warm2 they have tried to catch with red tint2 and increased color to 61, make sense, but white stayed on more vibrant side with warm1)
