It does correctly play back dual-layer DV if it is muxed into MP4 format, as described in this thread (meaning no HD audio). However, it doesn't play back dual-layer DV in M2TS format.
If you try and play a file like that via DLNA, it plays as HDR10. If you copy the file onto an external drive and connect directly via USB, then you'll get Dolby Vision output, but it still isn't actually reading the DV metadata from the file - instead it is simply reading the HDR10 stream and then converting that to DV on the fly.
The results still look quite good doing that (and if the M2TS file is only HDR10 in the first place then it will convert it to DV, and that can look very good); but it's not the same as actually using the dual-layer DV information in the file.
Even when both the player and the tv are showing dolby vision, it's still faking it? because that's what happens I play both a uhd disc and an m2ts from usb hdd. there's no difference I can find in any setting or menu or info display that is different between disc and m2ts usb. how is one to tell? I can see it being fake over dlna though, where only one of the two devices is showing dolby vision - as I said it seemed iffy, but I honestly can't see the dif with disc vs usb...
From that screenshot you posted a couple days back with playback of the .m2ts over USB it only shows the DoVi coming from the TV. It doesn't show it is getting DoVi from the x700. Can you please double check? Every .m2ts I tried (I tried a couple for sure!) only showed hdr10 from the .m2ts on the x700, but DoVi on the TV cause it was being converted as described by @shasarak
