It’s pretty new
Almost all TVs come with a power saving or eco mode enabled by default which ruins visibility. Find that in the settings and turn it off. You should also turn off motion interpolation (e.g Trumotion, Clear Motion Plus, Motionflow) so motion doesn’t become a smeary and artificial mess.



Set the gamma to 2.2 and make sure the eco mode is turned off.
You should also select the 2.0 audio track when available, or try the dynamic compression/volume normalisation setting.
