I followed this step. Was it overkill?

You mean the web page link?
That's just how a web server (Apache) looks when you allow folder access. I just put the images in a web server folder and linked to the folder. I run the web server on my home server and I bought a domain name nicko88.com because my name is nick and I was born in '88. It was available and it's short and easy to remember so I like it.
Personally I use the same settings for all resolutions.
2160p content naturally has 3840x2160 luma resolution, and 1920x1080 chroma resolution. So for 2160p content only the chroma is upscaled from 1920x1080 to 3840x1260.
1080p Content naturally has 1920x1080 luma and 960x540 chroma. So for this both are upscaled to 2160p.
What you need to understand is that the NGU upscaler is a pixel doubler, so it can only double the pixel resolution with 1 exception and that is NGU AA. NGU AA can scale from any resolution to any resolution. But I don't recommend it for luma (image) upscaling.
So now for up-scaling 720p to 2160p, NGU will normally scale it first to 2560x1440 (double), and then to 5120x2880 (double again) which is greater than 3840x2160, so then madVR has to downscale it to 3840x2160 to display on the 4K display. This is why setting good downscaling settings is important even if you think you are only upscaling. You can see in my upscaling settings I have luma quadrupling set to direct quadruple high. This is because very high image quadrupling is just a little too much for my 2060, so when I am playing 720p on my 4K display I am just getting NGU High instead of very high.
So you can see that even without profiles, an understanding of how things work and with careful settings, you can achieve what you want. There is nothing wrong with profiles, I just find them unnecessary for my purposes.
The biggest use of profiles IMO would be for image enhancements. However I don't find that I like any of the image enhancements normally except for a rather weak "1" for enhance detail applied to everything. Too much image enhancement just leads to too many artifacts IMO.
Also for color space I have madVR set to BT.2020 and my projector is also always in it's BT.2020 color space mode. So madVR maps both rec709 content as well as BT.2020 content to BT.2020, so the color always shows up fine. I don't need to have a rec709 profile mode in my madVR and I don't have to change my projector mode for HDR vs SDR.
I could talk about a lot more stuff but I don't want it to be overwhelming. Hopefully this teaches you some more of the concepts for now.
