The etymology of miniature was news to me - South Asian artists have been decrying the term as colonial as of late and this provides some important context
Please let me introduce you to the concept "Persian Miniature", it even has a Wikipedia page: https://en.wikipedia.org/wiki/Persian_miniature
There is also the equally (if not more) well-known concept of "Chinese Miniature Painting". Example: https://www.metmuseum.org/art/collection/search/36047
Both of these traditions are very established in Art History and any hypothetical tie to Western colonialism is, well, fully absent. That said, do a search using your favorite search engine. Miniature is not exactly a niche concept, so you will find lots and lots of great (small) stuff.
