Description
When zooming far in, it looks like both the mapbox.terrain-rgb and my own bathymetry based terrain rgb tiles have only meter vertical resolution. However, at least my bathymetry data set has higher resolution.
Here is an example with the bathymetry tiles.
Here is an example with mapbox.terrain-rgb.
Do you have an example where mapbox.terrain-rgb shows shadows from vertical sub-meter resolution?

Research direction
Reproduce the reported zoomed-in hillshade behavior using the bathymetry and mapbox.terrain-rgb examples, then trace raster-dem precision through hillshade rendering. Done means sub-meter vertical detail is preserved in the rendered shadows for both sources.
