I'm afraid this is the nature of local dimming on LED backlit LCD TVs.
If you want to get rid of the halo effect on white writing on a black background then you can only really achieve it with an OLED TV.
Blockiness (or posterisation) is usually a result of watching poorly encoded or low-bit rate content at high brightness. All you can do is turn the brightness/contrast down so it's less noticeable or look for a better source of the content you want to watch such as a 4K BluRay disc of a movie, rather than a compressed stream.
