The terminology then would be 'high aspect ratio emulsion'. Your usage would imply a thinner film.

To answer both terms then, Kodachrome is the thinnest color film manufactured and the most difficult to manufacture due to its thinness.

AFAIK, no t-grains were ever used in current Kodachrome films. The 400 speed Kodachrome and the rest of that generation which was never sold, did contain t-grains and had exceptional grain and sharpness.
