My emails with support ended at "we're working it".
Someone also mentioned the ATV4K is using something called DOLBY-MAT transport (?) which I'm guessing was not accounted for by Oppo. I asked what device they used to make the update as I thought the ATV4K was the only one using DV. Apparently the Amazon Fire TV 4K dongle does it as well. I ordered one to play with so we'll see.
There was also an issue uncovered with the HDMI-CEC option which keeps turning off the bypass device so you should turn that off for now.
Dolby Vision works in my setup via the HDMI after the update. Nothing special needed to be done. ATV4K plus Oppo 203 plus TCL 55P605 and tested cables.
