[Cin] Wide-gamut test page for browsers

https://www.wide-gamut.com/test My cheap tablet with Android 11 + firefox fails on both fronts. Interestingly, video embedded at first tab is just 8bit h264 according to mediainfo https://www.wide-gamut.com/assets/video-hdr/P3-BLUE-HDR-1000nits.mp4 Interesting to see that baaack in 2004 or 2005 when it was mostly research 8bit per component was considered ok for HDR video, but I guess further research disproved that early hope?
