Question Why is Yotube 4K picture is much better than my 4K file ?

[Dunhill79]

Hi Guys, I am using Monitor Philips Brilliance 328p which is a 32 inch 4K monitor. My problem is, watching the the same movie from Youtube and from my PC is totaly different quality .

In Youtube I see the picture is much clear and more real compare to watching the same movie using 4K file that I download . I am not sure why the picture quality is so much different. Refer to the pciture below for your reference. I really hope some one can guide or infomr me what did I miss ? Is it setting that I am not aware. I am using player VLC & KMplayer.

video from your file is 10bit hdr with 4:2:0 samples (15bit), do you have enabled HDR?
youtube version is 8bit SDR

Is whatever player you're using on your PC configured properly? Seems odd that a screencapture would actually show a difference (besides YT re-encoding).
