error H.265 videos "not compatible"

Trying to play mp4s from my Mavic2 in Quicktime. Getting "error: H.265 videos not compatible". Click on "tell me more" and this link pops up:

https://support.apple.com/en-us/HT207022

says they ARE compatible? It says specifically that Quicktime CAN.

"Support for HEIF and HEVC is built into iOS 11 and later and macOS High Sierra and later, letting you view, edit, or duplicate this media in a variety of apps, including Photos, iMovie, and QuickTime Player."

I just want to watch my videos in Quicktime. Simple. I don't want to have to convert them in Handbrake. That's arduous and takes time.

mac OS 10.12.6

Quicktime 10.4

DJI Mavic2 settings:

video size 3840x2160

video format mp4

color D-log M

camera video coding H.265

If I need to change these settings, I'll change them to may them Quicktime compatible. But again, the link above seems to say they are compatible.
