I notice BDInfo and VLC list the HDR10 streams at 3840x2160p, and the Dolby Vision streams at 1920x1080p. Does this mean Dolby Vision streams are only recorded at the 1920x1080p resolution?

Dolby Vision allows for a maximum resolution of 8k, up to 12-bit color depth, maximum peak brightness of 10,000 nits.
It's not important the problem be solved, only that the blame for the mistake is assigned correctly -
I thought I was specific and was asking if the Dolby Vision stream on my particular disk was only recorded at 1920x1080p resolution according to the details in my original post.Originally Posted by sneazzy95

Bluray has the ability to composite not only Text and Graphics (both as graphics, still or motion), and text via rendered fonts, but also a secondary video plane overlay on top of the primary background video. Note that unlike the primary, the secondary video cannot be full rez, as that would be too much of a bitrate and buffer burden.
So I am betting that the DolbyVision stream is the secondary video, and it overlays the primary. So while the image is 4k, the DolbyVision changes(HDR variations) in the scene are only 1080p. This is a compromise allowing reuse of the main material without exhausting the capacity budget of the disc, but at the expense of optimal ultimate DolbyVision detail.

I also found it strange why for 4K Dolby Vision the so-called Enhancement Layer is authored in 1920x1080.
This EL can be FEL or MEL. Where MEL (Minimum Enhacement Layer) is just a placeholder for Dolby Vision's metadata: RPU.
FEL (Full Enhancement Layer) also holds differential 10 bit --> 12 bit video data. That's why you'll see big differences in MEL/FEL sizes when you'd demux them.
Could it be that because of 4:2:0 color subsampling, 1920x1080 resolution is sufficient for 4K 2 bit additional color data? I always wondered... BTW if you demux a FEL and remux into a container, during playback you see a B/W-like image. Of course a Dolby Vision composer will process this information as it should.Last edited by Ennio; 9th Mar 2022 at 05:04.
