I'm not an expert in this space, but professional displays (e.g., screens mounted in airports, and the like) do not seem notable for their cinematic visual quality-- usually they have a washed out appearance. They're reliable screens, but not made for watching movies.

Can you be so sure it is the screens that are at fault.

When mounted in airports and the like, they are also mounted in environments where the lighting is usually such (i.e., much too bright) that nearly any screen (LCD or old CRT's) would generally appear "washed out". So the effect you see may not be the screens, but instead may be caused by the environments in which you generally see them operating.

Look for terms like “conference room display” rather than “smart signage”.
