Saortica Scenes with darker overall colors or stark contrasts I personally prefer the 1920p HEVC. Sometimes they are 2048p 2160p.
In brighter scenes it's less noticeable, the main advantage for choosing HEVC is, in most cases smaller filesize and lower bitrate. Which makes it easier for your network to handle if this would be an issue, potentially higher power usage with HEVC, Which by itself for me doesn't change much aside from the OGo shutting down faster on hot days. Mentioning this because I had this happen.
Now, I don't know if this is coincidence or not, because I don't really see a clear change in the metadata, but the past couple of days some 2400p are actually good. I think it's because of low complexity of the frames. Not an actuall setting. You can still see the difference if you know what to look for. But on the OGo with the video playing normally you don't see the artifacting yet do benefit from a slightly better sharpness because of more pixel filling.
According to the official numbers, you have full pixel saturation on the OGo at 5120x2560
As reference, 2048 is 4/5th saturation. (80%)
I'm also specifically talking about the OGo, The display in each headset impacts the picture differently, even if they would be the same resolution, there are other factors.
root I'm still checking, but I have an example almost ready.
