Hi Jody, single raster layer vs groups use different rendering paths, the single one uses the "direct rendering path" which does not go through StreamingRenderer, but uses pure JAI for better performance and scalability. That said, if you are not able to reproduce the same issue in a different setup, something odd is going on.
I've just tried setting the WMS interpolation to bilinear in the server configuration, and running on the spearfish group, the dem is interpolated with bilinear, even with high oversample (keep on zoomin in). Also tried putting the dem in a mosaic and using that in a group, still interpolates as configured... I've tested on 2.17.x, because that's what I had handy for a 5 minute test.
