In a review of the Met's [in New York City] new Islamic Galleries, “A Cosmopolitan Trove of Beauty,” by Holland Cotter, published 10/27/11, New York Times:
“The new, much expanded installation — organized by Sheila Canby, the curator in charge of the department of Islamic art, with Navina Najat Haidar as project coordinator — is as intelligent as it is visually resplendent. The art itself, some 1,200 works spanning more than 1,000 years, is beyond fabulous. An immense cultural vista — necessary, liberating, intoxicatingly pleasurable — has been restored to the city.”
Would 'resplendent' be an hyperbole [GRE #35] to describe your local art gallery, or convincing?
Resplendent: Attractive and impressive through being richly colorful or sumptuous.
