Sure, that's what the TV has, at least what I see on my Radeon settings and on the TV settings, it has 10bit and 12bit modes but I don't trust the 12bits mode till I test it myself. It also has a "HDR effect" image mode which is, as I suppose, what you're referring to, tho I just use game mode since image quality (brightness, contrast, color balance and black levels) are high in my eyes. For reference, I had a gaming monitor till I moved to my current country with 1000:1 contrast and it looks exactly the same in that regard. I also have a cheaper TV set in the bedroom for netflix and shit and it looks nowhere near this one.
Edit: Ok, just confirmed and you're right, tho I don't use HDR mode, I use SDR which is very good for a TV of this size/price
