Typeface for Whitney Museum (not H&FJ Whitney)

Hi. Does anyone know what sans the Whitney is using these days? It's not H&FJ Whitney.

Looks similar to Calibre, but the "a" is wrong.

The restaurant uses Univers for its logo and menu, and the Biennial uses Bell Gothic for its labels, etc. (Not that that helps.)
