Dolby Vision Profiles

Hey everyone
Does the ATV4K support other profiles besides profile 5 for Dolby Vision?

I have some profile 4 & 8 I was testing but they only play in HDR, not Dolby Vision.

Single layer of course, they play on the 2019 Shield as DV, but not on the ATV4K

Specs are on apples page

Only profile 5 is supported.
