Picking nits;
Mirriam-Webster is American English.
OSM policy is to use British English ... so the Oxford Dictionary should be used.

Many many key/values are not precise in what is intended. That is why 'sub keys' are used.
'Sub keys' like width, height add detail. If you think a gallery needs more detail, add sub keys to it!

A 'nice key'?

Tourism? Visiting a place for pleasure? Looks to be the correct key to me!

No. OSM amenity - important facilities.

Tourism is the correct key in this instance, a place that provides visual pleasure.
