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

Only profile 5 is supported.
