Hi,

I suggest attend a demo yourself for Sony and Samsung. Some differences between x90l and 85d:
- Sony dimming has superior shadow details but at the expense of blooming though this generation of Sony's blooming control is better than previous generation
- Samsung has less blooming but at the expense of shadow details
- Sony has better upscaling of lower quality video and motion compared to Samsung
- Samsung will appear higher contrast with better blacks
- Sony has more natural color while Samsung is more saturated and colorful
- Sony and Samsung has narrow viewing angle..so sitting far away from center position , color and image will appear washout

Some of above differences will be more prominent in a dark room but if you watch with lights on in a living room, actual perceived differences may be minimal.
Also as both manufacturers have different approaches in designing their TV, some of differences like color, blooming control, shadow details is up to your personal preferences.

Hi,

LC C4 is quote good. It can satisfy most of the consumers. Its only limitation compared to mini LED TVs is lack of brightness and its white is not really pure intense white especially in HDR.
It has a very glossy finish screen. Some prefer matte finish.
The advantage of OLED contrast and black level only shines in a dark room or dim room with little light source.
If you watch in a bright living room, you won't fully utilize its potential. Can save some money go for mini LED TVs with bigger size. That is my opinion, as I own QLED, OLED and miniLED QLED TVs.

If yr budget is similar to LG at 20k, the best 85 inch TV at that price is Sony Bravia 9. It has similar black and contrast as OLED.
Now Sony got offer

Problem with Apple Vision is only for 1 person...If you need to watch with your families and friends which is quite common at home..you need a few pairs of Apple Vision which ends up costing a bomb
