You are in a minority. Anime is easier going - except the old stuff with jaggies and colour bands etc, when not intentional!
For the money and top tier status, people expect these to be general user great and to mask/better older contents foibles instead of highlight them. It's understandable.
I get it. I just think its a limitation of using a 4k panel over a 1080p panel. There is only so much image processing can do, and in my experience, even the best in class image processing (without a dedicated video processing box) still looks fairly pants.
This IMO is not an LG specific issue. Its an tech issue. I've seen LG, Panasonic and Sony and I personally think that although some are better than others, none are really mindblowing with low bitrate content compared to my Samsung plasma.
I have similar experience with 1080p video games. Sadly they just look pants on a 4k screen compared to a 1080p screen. The only software magic I'm aware of is integer scaling for video games which helps substantially.
People can save A LOT of money by going with a native panel which suits the majority of their content rather than the panel which reads as having the best specs on paper.
For the average person watching BBC news and Eastenders everyday via their aerial, a 4K HDR anything is a waste of cash. If they only watch the rare HDR film, they'd be better off sacrificing that and enjoying the majority of their content in the best way possible IMO.
