what is a dual-track and dual-layer exactly? can someone describe in simple terms?
Dolby Vision is really complicated, you may want to do more research to learn how it actually works.

In human words:
BL(base layer): an HDR10 2160p YCbCr 4:2:0 10-bit video.
Dolby Vision fall back to this when not supported.
EL(enhancement layer): an HDR10 1080p YCbCr 4:2:0 10-bit video.
Supported device use BL and EL to mux a final 4:2:2 12-bit video.
RPU(reference processing unit): To indicate how filmmaker would like the video to be separately shown on 100nitSDR/600nit/1000nit/10000nit display. (despite the actual brightness record in BL)
There are basically 4 types of Dolby Vision video:
Profile 5(streaming): ICtCp 4:2:0 10-bit video + RPU.
It uses a more efficient color coding, but appear green and purple on non support device.
Profile 8.1: BL+RPU
Profile 8.4: Dolby Vision shot on iPhone, HLG BL+RPU
FEL(Full Enhancement Layer)
Profile 7 DT_DL FEL: BL in one video track, EL+RPU in another video track.
Profile 7 ST_DL FEL: BL+EL+RPU in one same video track.
MEL(Minimum Enhancement Layer)
Profile 7 MEL: BL+RPU same as 8.1 just in bluray container.
Please don't hesitate to point out my mistake!

I still have one of these Oppo bluray player clones which is basically the same thing but without the disc-reader.
Perhaps somebody can recommend some good (FEL) movies where the DV really stands out and make a difference?

This thread has a lot of useful information and catalogs 99% of the discs released with Dolby Vision:

There's a link in RESET_9999's signature that breaks down DV support across several devices. Including the Oppo.

Hey RESET, is there a way to generate a P7 RPU with an xml file from resolve. Keeps defaulting to P8.1

Not directly but if you have the original P7 RPU and you used the original scene cuts, you can copy the metadata levels from your P8 RPU with workflow 2-6.
I did it a couple of times for some static P7 movies like Avatar.
Example:

Are you able to transfer levels from a cmv4.0 rpu to a cmv2.9 rpu? Or is that not possible yet?
Re: Dolby Vision now possible through MP4 Mux.

You can only copy levels that already exist in the original RPU. So you cannot add a cmv4.0 bloc to a cmv2.9 rpu.

so before buying a new TV, is there a need to check for CMv4 support? I've not seen a spec sheet that goes to that level of detail.

They don't make new TVs with older cmv2.9 chip anymore. So any TV after 2019 is most likely cmv4.0
