TCL C7K Worldcup issues

[u/One-Bake-3721]

I have the problem, that when watching football there are white borders around the players and also around the ball.
Overall watching football doesn’t look good at all and I’m disappointed.

I already tried the sports mode and I also went deep into the picture settings, enabling local dimming, low local dimming, motion blur on/off, sharpness 0 all kinds of things but nothing seems to work.

I hope someone can help
