I would say rather it's a workout for the gray scale tracking and CRT color purity. When we demo these old sets today, we actually have a better chance of good pictures, because all the gray scale and shading problems that often cropped up in tube broadcast gear are non-existent in modern restorations.

That's fair. That said, I've found matrix issues to be MUCH more noticeable with very subtle color.

I've seen tape from a TK-26; it was... interesting looking, to say the least.

Even the Astaire and Eisenhower tapes reveal a lot of issues that would probably have gone unnoticed by the average viewer at home.
