This may not respond directly to your query but hopefully will help you make up your own mind about the age and authenticity of your purchase.
The first link below shows an eBay auction from Mainland China with a ten-inch diameter variant version of your bowl featuring red external glaze and much the same painting in the cavetto. The seller has it listed as an antique and claims it's Ming-era from a small village in China. The asking price is US$498 plus US$50 for shipping. Really cheap for nice Ming, I'd say.
The second link below, from the same seller, shows another ten-inch bowl with your same external motif but a qilin pattern in the cavetto. This is typical of how Chinese porcelain makers mix it up by issuing variant patterns like these. Early in the 21st century they were making clones of 18th century famille rose export patterns and slipping them into the US market in matching pairs via cooperative eBay sellers and live internet auctions. Some of these early fakes were fairly good but most were detectable as new and somewhat easy to spot because of being sold in pairs. Now, the fakes are getting better and harder to spot, with the practice of selling them in pairs seemingly less in vogue.
Keep in mind an important point: No matter how high a price a Mainland seller may ask or what kind of claims they make when pitching their product to foreign markets, any true antique is apt to be worth vastly more when sold on China's domestic auction circuit. If you don't believe it, just look at the mega-prices Chinese buyers are plunking down for authentic items being sold by Sotheby's and Christies.
