Same video in HDR and SDR for comparison - Q9FN HDR Problem

Hello everyone,

getting straight to the point I need to download same content with HDR and witout HDR (some quality demo or something) so I can compare both vidoes and see if I got faulty TV. I am suspecting that there is something wrong with HDR because most PS4 games seems to have higher peak brightness in SDR than HDR (SDR backlight 24/50, HDR ofc 50/50). I am sure that my TV is properly set up and connected - it detects HDR content. The problem is... this HDR contend does not look much better than SDR.

- I bought new TV - Q9FN and HDR is... not what I expected. I was using 10 yo Samsung TV so the diffrence should be noticable.

I am 100% sure that everyting is set-up correct. My TV shows its HDR signal but... I really can't tell diffrence between HDR and SDR. I am using primaly PS4 to check HDR effect - because I can turn HDR on/off very easy in most games).

In Red Dead Redemption 2 game in HDR looks worse than in SDR - I can tell that peak brightness is higher in SDR (backlight 24/50) than on HDR. Same with God of War - I heard that HDR in GoW is superb but I can brely tell diffrence.

I got professional calibration for SDR content but not HDR. For HDR I am using Local Dimming High and Contrast Enhancer, eco off and LCD motion off.

2 examples: https://samples.ffmpeg.org/4khdr/

More samples here, but no SDR and HDR of the same video: https://kodi.wiki/view/Samples#4K_.28UltraHD.29

There are other sites with HDR samples on the web.
You could download from Youtube the SDR and then the HDR versions separately.

UHD Colour is On. HDR+ Mode off. I am not impressed by HDR in most games on PS4 but yesterday I checked Uncharted 4 and I think in daylight scenes HDR does gr8 job.

I also run multiple brightness test - static boards, clips etc. and I came to conclusion that my TV can give super-bright image. I think I just need proper sources of content : > Anyway thank you guys for help.

<-- This clip absolutly burns eyes (I know it's not natural, just wanted to check if my TV can give about 1500 nits). I just need better sources of high quality materials.
