Old schematic vs new schematic reading - night and day

I was fixing a 1982 Marantz receiver last week and had to pull out the original paper schematic. Man, those old diagrams are beautiful - everything labeled clear, parts numbered in order, no guesswork. Then I went to look up a board for a 2018 Samsung TV and the PDF was a grainy scan with parts all over the place. Has anyone else noticed newer service manuals feel rushed compared to the old Japanese stuff from the 70s and 80s?

And on top of that, why is it so hard to find the actual part numbers on these new schematics? I spent an hour cross-referencing five different pages just to figure out one capacitor value on a modern board. The old Marantz stuff had the parts list right there on the same page or the facing page, all numbered in a logical flow. Do you think the rush to put things in cheap PDFs is just manufacturers saving money, or is it something else like they don't care if you can fix it yourself?

That Samsung PDF being a grainy scan is insane. In 2018 they couldnt even bother to get a clean copy of the board layout. Old Marantz stuff had actual draftsmen drawing those by hand and it shows.
