JSON.parse() on Buffer gets parsed as <Object object> instead of <Buffer> Node JS

It looks like JSON does not parse into an actual type. Is this normal and expected behaviour for JSON.parse?

let parseBuf = JSON.parse('{"type":"Buffer","data":[146,247,204,173,154,172,70,6,147,130,219,222,4,69,161,74]}');
let bufferBuf = Buffer.from(parseBuf.data);

console.log(parseBuf instanceof Buffer)
console.log(bufferBuf instanceof Buffer)

console.log(JSON.stringify(parseBuf))
console.log(JSON.stringify(bufferBuf))

Results from the console log is

false
true
{"type":"Buffer","data":[146,247,204,173,154,172,70,6,147,130,219,222,4,69,161,74]}
{"type":"Buffer","data":[146,247,204,173,154,172,70,6,147,130,219,222,4,69,161,74]}
