HDR thats handcrafted by the devs and considered in the art pipeline from the start is often disappointing, let alone added at the end of developement or even post launch. I'd imagine HDR done automaticially would be pretty cruddy and about as good as dynamic tonemapping in modern TVs, and maybe not even as good as most implementations of it.
People who purport themselves as hobbyist-semi-experts in HDR implementation like EvilBoris (who has worked with Moon Studios recently on the Ori 2 PC HDR patch) produce their own HDR content that looks like total crap to me and I really hope they don't become the arbiters of what HDR should be in games. I just stopped watching his HDR conversions because they either look really gaudy and overdone or have weird issues that apparently look normal on his setup. Check out his last few vids where he has converted next-gen trailers that are SDR to HDR by converted the colour space and increasing the dynamic range, they look horrible to me and he is doing this by hand on a (presumably) shot-by-shot basis:
Here you will find various experiments I am running for my HDR analysis. You may even find the odd grading attempt, to try and re-grade an old game, into a m...

Here is one of the headscratcher shots for me (This is over on Vincent Teoh's HDTVtest channel instead of Boris' youtube channel), he says there is a problem with overbrightening here and it makes it everything too bright... he doesn't mention that all the colours are completely fucked up and oversaturated and the image just generally looks awful, maybe he didn't see that on his end and its a problem with the final video output? I've seen him say that this sort of image looks "good" more than a few times now and I just can't take him seriously now because of that:
What I'm trying to say is that this part of the video is so different to everything else he shows that it looks to me to be an actual problem with the output and something went wrong there for it to look like that, but he seems to think thats just how the game should look in that scene, puzzling to me. If I saw that image after having seen the flatter image from the rest of the video for the whole game I would immediately assume the output was wrong or the TV hadn't switched to HDR properly, its just not correct imo.
I was very disapppointed with the Ori 2 HDR and kinda confused as to what they were going for with the default settings, they looks absolutely awful to me and I tried to ask EB and one of the lead devs about it directly on the other forum but their answers were completely non-specific and generally not useful so I just gave up and played it in SDR after a month.
That’s just when the original blog post went up with the expected fixes. They announced it on their Twitter today that it’s out after being delayed. Sigh this is such a bummer, I bought the collectors edition and now I just feel silly. Feeling like I’m going to have to wait till the end of the...

Below are my screenshots to show how fucked up the contrast is at default settings, it nearly looked correct at the minimum value of 0.5 but I still needed it to go lower to not look like bad tonemapping of SDR and they didn't really help me out with my "problem" in any way. Its like they made the default settings for really low contrast IPS panel TVs and if you have a really bright FALD you are just shit out of luck. If you look at the 2nd picture you can see how the shadows are crushed and highlights totally blown out at default contrast setting of 1.0 and then in the 3rd pic its better, with a less flat image than the SDR pic but it still has a loss of shadow detail and slightly blown out highlights that I don't get at all on SDR:
I find that really weird since I know EvilBoris owns an OLED so presume he did most if not all of his testing on that. I imagine the default setting of 1.0 for contrast would make the shadows very hard to see in a lit room on an OLED, plus the fact that my FALD will be elevating those shadows a bit due to the limitations of the tech not being able to show the true brightness level of the those pixels. He did say in one of the replies that he uses the minimum contrast value of 0.5 like I settled on which begs the questions, why wouldn't you increase the range if your sweet spot was the min value? I'm so bloody confused.
TL;DR - HDR is hard to get right when you do it by hand, auto-HDR will most likely suck imo. I found some HDR lacking in recent games and tried to ask HDR enthusiasts and devs who worked on the games why I was seeing what I was seeing and their answers were either lacking or milquetoast. You know when you are talking to someone about something technical and then you point something out and they can't explain why its wrong or argue that there isn't a problem and you think "hmm, maybe this person doesn't know as much as I thought they did" lol.
