I had no idea that every demo and trailer was being offered for free. It seems to me that publishers and studios are missing a trick in this regard, and in keeping with their legacy of not paying for content, they could reduce home video consumption and save money, by simply charging for the downloads.
I wasn't aware of the Dolby Atmos sound formats until I installed your files. They're only available as a downloaded Dolby Atmos demo, but when I ran it I was pleasantly surprised at how good the sound quality of it was.
The only issue I found was the viewing angle of the Dolby Vision sample. It's a good demo, but it was too sensitive to how the video was being viewed. If I held the screen at the right angle, the image would get scrambled. The THX samples looked good, but I believe there was a problem with the DTS audio demo, because it's decoded in the TX3, but it doesn't work. I can confirm that the Dolby Atmos demo plays well, and works with Dolby Vision content.
I was also quite impressed with the HDR10 demo, and the THX VFX demo looks amazing. I was also able to demo the Dolby Vision demos with HDR10, but they were not perfect. I would say that the Dolby Vision demos were slightly better than the THX VFX demos, but there was still a bit of a greenish tint in the foreground and there was noticeable pixilation on the Dolby Vision samples. This was mostly in the THX VFX demos, but for some reason THX VFX is using a very high-quality panel and the Dolby Vision samples are low-quality panels. You can tell the difference because the THX VFX demo looks very good, whereas the Dolby Vision samples look quite poor. 827ec27edc
