I thought we have some tests that use spir-v when present: https://github.com/llvm/llvm-project/blob/e4060d3beab3b525b49baaa15484e3c595740a2f/llvm/test/CodeGen/SPIRV/empty.ll#L2

Could we do something similar in mlir spirv serialization?

If this is not straightforward, validating by hand is also fine IMO.
