Are the Ultra maps worth getting?

Getting ready to pull the trigger on a EC 93sv. There is a rebate if I get the Ultra maps. Are the Ultra maps worth getting?

Here is what the Ultra accessory card provides over the standard LakeVu mapping:

Is it worth it for you? You need to search the lake finder list to see what features are available at your home lakes here:

They may be for your lake, but for mine, I'm a little disappointed. The contour lines seem to be the same, the main difference is that the map card includes relief shading and "fish eye 3d" view and let you adjust the lake level dynamically. I was excited about the contour relief shading but in practice have been THOROUGHLY disappointed in it. On both the ActiveCaptain app and on my EC 93+ unit, the shading gets very pixellated if I zoom in, and for essentially all purposes the contour lines seem to share the same info more effectively.

Now, the Fish Eye 3d could be REALLY helpful if I were to go through a submerged stump field and precisely mark every stump.. but that would be a PITA. Otherwise it seems like a thoroughly inefficient way to convey contour info.
