The real HDR has wider color are, so less banding in gradully changing colours.
Also HDR means wider dynamic in colours and contrasts and brightness.
So it reguires a lot of new hardware and also material that is made in HDR. Is the material is not made in HDR mode, it should look just the same in HDR and non HDR devices.
And then there of course are those chips that artificially try to "improve" the normal picture to look like a HDR and those are bad...
Forgot to post this when i wrote it, so i ended up posting something else first.
first, that sounds like they are bringing 10 bit to mainstream devices, 8bit was 1-255, 10 bit is 1-1024, working with a dslr that takes 14bit raw photos, Its easy to see how that effects photos in editing, I may not see all the color due to a monitor that may struggle with 8bit (not 100% sure here) but Its plain to see when you push something and the banding does not happen
The contrast in dark and bright should be again 1-1024 like a the color, but outside of oled, I don't see the contrast ever being great. Having seen an oled tv right next to a high end lcd... there's no comparison, the oled curb stomped the lcd, I knew there was going to be a difference between lcd and oled, but damn didn't think it would be that massive in just the contrast alone.
Personally, I turn off all dynamic contrast stuff on my tv's because what's this, the screen is dark, and the backlight turned off so now its WAY to dark, oh, it went to a sunny scene, and a second or two later it decides its not going to be dark again so it turns the brightness up. I cant express how distracting this is to me.
