If you want to see the nameservers listed by the registrar, those are available in the DNS system via the root servers.

For example:

 dig @a.gtld-servers.net ns stackoverflow.com

; <<>> DiG 9.10.2-P4 <<>> @a.gtld-servers.net ns stackoverflow.com
; (2 servers found)
;; global options: +cmd

If you modify the name servers listed in your registrar account, those servers will be reflected in the root / gtld servers. When you modify your DNS zones that your nameservers serve, they have no effect on the results returned by the root servers. Additionally, the only records the root servers will return are NS and A/AAAA defined by the registrar for the listed NS records. These are just pointers to find the authoritative (per the registrar) name servers for a domain to send your queries to.
