What is strange about it? It's HLG and so will play "OK" as SDR.

BTW, sorry to say but your English is borderline understandable. Try full sentences, each expressing a single coherent thought.

You can just compare 20190511-152944_RTL UHD_flag.ts (67MB) https://yadi.sk/i/985DVw34OHQrrA I've uploaded in this thread before with present 20200926-153844_RTL UHD Austria.ts (232 MB) https://yadi.sk/d/_4Oo1_awZEQr4g (20190511-130113_ARENA HD_flag.ts (38MB) https://yadi.sk/i/HiuZ5Rb2RKkc0g SDR for control) with EVR (not EVR-CP to avoid any post-processing in renderer) in MPC-HC and if you have good monitor and eyes I believe you'll see difference as minimum in red color in top left corner
Btw today's F1 race translation fully prove I was right - in some seconds before adv someone was switching from non-HLG to HLG and vise versa - I hope to cut and upload an example(s) in days.

You're welcome but i.e. when I gave just link on this thread to a smart Russian guy Iron_Butterfly (I even didn't new he's shader writer that time) he fully understand me and at first correct not working MPC-VR's correction_hlg.hlsl shader (so modern versions of MPC-BE do HLGtoSDR with i.e. EVR-CP but red becomes some rose due to wrong and non-adjustable constants) and then wrote new working shader I successfully use in app SmartDVB or MPC-HC. Here's two shaders with my constants 1000.0&300.0 and 150.0&0.5 https://transfiles.ru/l99ql - in original was 1000.0&80.0 and 100.0&0.5
Even nevcairiel well understand I ask him but he implement in LAV Video Decoder useful thing (like NVIDIA CUVID h265 10bit decoding or switchable CUVID DXVA processing for playing "broken" streams in Win7x64 with hardware accelerations without artifacts on nVIDIA videocards) in years but not all frame decoding - I agree he calls simpler "skipping" (this function is in ffmpeg) he don't want to implement despite of it's very easy to do, proved by Aleksoid1978 and MPC Video Decoder.

It's hard to write hard enough things with simple sentences
If you or someone can't understand whole sentence try to read without () and then in () and summarize them in your brains because I believe each word I write is important

Here's a sample I promised to upload 20200927-141013_RTL UHD Austria_.ts (108 MB) https://yadi.sk/i/FInnqG3BbHt5SQ - when watching with EVR (so without processing) between 5 and 6 seconds red Ferrari becomes some orange (so video beginning from 6th second becomes ordinary HLG so shader and i.e. EVR-CP become necessary to watch Ferrari in ~ normal color on SDR - so non-BT.2020 - monitor).
One more thing - rectangle STRECKENINFO GP VON RUSSLAND without shader is some orange too but see letters carefully - with EVR and in VLC they are looking well but with shader+EVR-CP and in mpv letters with visible artifacts.
PS. On my PC EVR-CP some times stutters while playing RTL UHD but VLC with OpenGL always fluent - can someone confirm that?

Here's one more vise versa sample 20200927-151917_RTL UHD Austria_.ts (58 MB) https://yadi.sk/i/n2vgJY5IZGg_Fg
without HLG processing at 8th second i.e. orange adv banner "Emirates FLY BETTER" becomes red.

I've watched 20200927-141013_RTL UHD Austria_.ts and 20200927-151917_RTL UHD Austria_.ts on Samsung QLED 43" supported even AV1 4K 60fps playing and it shows wrong overcontrasted and oversaturated video while non-HLG in that files and normal video when HLG in same videos.
PS. Letters on STRECKENINFO GP VON RUSSLAND looks like in VLC so good enough (but not ideal).

Btw I've reupload that two shaders to more permanent place Shaders.7z (2 KB) https://yadi.sk/d/-DUfaqlY6LfxtA
