Color Print Management and Lightroom Classic?

Just a conversation.

Over the years of color workflow I have experienced a lot of confusion and mixed results trying to manage my color output. I spent a lot of time getting the correct icc's, making sure my management was properly setup and doing test prints until I was able to WYSIWYG for photographs.

These days it just all seems to work better? But what I really dont get is why? I have lots of different paper stock and I am not using any icc's and the print workflow is very basic-but the proof is that the prints tend to look great on the first )or sometimes second) try. 

I still feel the page setup-printer setting-print dialog-print configuration is all way to cumbersome, but again the prints look good? 

Why?
