Update the tutorial files and docs with higher grade content?

I recently watched a quick tutorial about making a better looking landscape material on YT. This is one of many out there. But when I go to start working on a landscape in UE4, under Engine Content I get a very rudimentary material that looks terrible by default. Even the tutorial for landscapes in the documentation gives a dreadful end result. Similar situation with the new Learning videos tutorial.

UE4 is known for coming with many lighting and post-processing presets that make things “just look nicer.” (For example, Unity comes without those, and users need to find and follow a tutorial to fix that and get similar results.)

Why not apply this same successful approach to all the other tools? At least in this case, let the Engine Content include a few more advanced and useful materials that “just look nicer.” Or replace the old ugly default with a new one that looks like landscapes in 2020?

Thanks for caring about us filthy casuals.
