Yep. It's almost definitely a Dolby Vision layer.
@Ghitulescu if you see something like this:
It's Dolby Vision.
Basically there are two layer: the first one is a normal 3840x2160 10bit H.265 stream and the second one is just "data" which you see as 1920x1080 H.265 10bit but you can't decode separately otherwise it will be just green.
The idea is that:
A) If the decoder is Dolby Vision Aware, it will find the second layer and use it in conjunction with the first to create a 3840x2160 12bit HDR PQ stream to the TV.
B) If the decoder is NOT Dolby Vision Aware, it will ignore the second layer and play the first one as a simple HDR PQ 4:2:0 10bit 3840x2160 stream.
