The NativeImage is a generic class, it should support most image format. I am glad to hear it support your test big tiff but we cannot make sure it support all the big tiff file.
We have some special class for example ECW, GeoTiff, Jpeg2000 etc. You can search them here: https://www.nuget.org/packages?q=ThinkGeo.MapSuite.Layers
If you want to render a special type, you can try to render it by its special class first, then try to render it by the generic class.
We have a wiki page about it: https://wiki.thinkgeo.com/wiki/map_suite_data_format_guide
Wish that's helpful.
