json rpc – How does the isinitialblockdownload field in getblockchaininfo bitcoin core RPC work?

Let’s say you have a running node and it returns fully synchronized for 30 days. showisInitialBlockDownload: false. Will it show up if I turn it off? isInitialBlockDownload : true What if I restart the node? That is, if initialblockdownload is set to false, will it be set back to true if resync is needed?
