So, YES, it WAS photochemically possible (especially in the 1980s) to achieve the color range of "teal" (actually cyan and cobalt blue).
One is GLOBALLY, where the shades (for instance: cyan/cobalt blue) are attributed over a wider range of colours thus appearing like a layer spread over the whole frame and all colors rather than accentuating specific colours only).
The tonalities of Blue/Cyan and golden Amber were very much possible and part of the DeLuxe color process and later also others, partially seen already in the 1950s an 60s.
Cyan and cobalt blue are not the same color. Cyan is a nearly even blend of blue and green. So is teal. Cobalt blue is a cool blue, much heavier on blue than green.
When people refer to the "teal look" of modern movies, it's the heavy presence of green in the blues that they object to. Cyan and teal are both gaudy, ugly colors that were not prominently used in movies until the advent of Digital Intermediates in the early 2000s. The teal/cyan bias is a modern trend in color grading.
Suppose in 15 years, another fad sweeps Hollywood, and fillmakers decide to replace all the red in their old movies with flourescent pink. Do you not see how some people could find that appalling?
In some shots of the new BD, the emphasis (saturation) on cyanish tones is a bit too much (but specifically night scenes were lit in cyan[!] so it has to be there)
Scenes in The Terminator were lit in blue, not in cyan. The "steely blue" was Cameron's signature style when he made movies like this, not "steely cyan."
