Two of the reasons I shared the output from my PineTab2 were:
1) my output had several properties that yours didn't
2) the reported sizes, which seem related to resolution, were much
   larger then with me

There was a recent thread on linux-rockchip about AFBC and that rk3399
doesn't support that with resolutions > 2560x1600
https://lore.kernel.org/linux-rockchip/20250417065759.5948-1-m...@etehtsea.me/

Dunno if such an issue could be at play, but I figured I'd share it in
case it could help.
