Oh interesting! The only issue I can see here is if you’re zoomed out, tiles will start to disappear because it assumes the loaded parent that meets the lower screen space error is sufficient.
Here’s what this looks like for the photogrammetry example on Sandcastle for anyone who wants to see this. It only loads higher resolution tiles, but tiles will disappear when you zoom out.
I think a better workaround for the skip lod artifact here that I just discovered might be to tweak the baseScreenSpaceError:

So I would try lowering it so that all tiles in the first couple of levels are loaded. Let me know if that helps.
