4k vs HDR vs OLED...
Is it worth paying a lot more for an OLED TV? Is the difference in picture that great vs a 4k HDR LED?
4k, hdr, and oled are not mutually exclusive.
- you can have a 4k tv without hdr that is not oled
- you can have a 4k+hdr tv that is not oled
- you probably cannot have an oled tv that's not 4k+hdr (at least the newer models - old models could be 1080p and non-hdr)
To actually answer your question, yes, it's worth paying more. The image is incredible. Much like plasma, there's no "backlight" to an OLED tv. Each pixel is an individual light that produces the primary colors, and more importantly, can shut off. That means you have basically unlimited contrast and black levels that approach "zero" (or infinity?). It's almost ridiculous how much nicer they are than traditional LED technology.
It does have drawbacks; namely burn-in (like plasma) can occur. It's not as bright as regular LED tech, though, in an isolated environment (ie: not right next to a maxed out led tv) you'd be hard pressed to notice the slightly dimmer picture.
If you're willing to pay for it, it's worth it 100%. If you have some capacity to wait, there's some new technology in the pipe, called MicroLED. It will behave much in the same way that OLED does (individually lit pixels) and bring all the OLED benefits without the drawbacks. It will not be susceptible to burn-in, and will be bright as shit.
