case sensitive/in-sensitive match not working in nginx

in my server directive, the location configuration are as below

    location ~ \.(html)$ {
        expires max;
        return 200 "case sensitive match";
    }

    location ~* \.(html)$ {
            expires 10d;
            return 200 "case insensitive match";
    }

My expectation is that when I load localhost/somthing.html it should print case sensitive match and when I load localhost/something.hTML it should print case insensitive match

However, in both the cases, case sensitive match gets printed

The request log in access.log is

127.0.0.1 - - [18/Apr/2021:17:56:15 +0530] "GET /something.hTML HTTP/1.1" 200 20 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.0.3 Safari/605.1.15"

Attached picture, see the statement printed and also the expires which is set to MAX proving that case sensitive match worked. What could be going wrong here?

location ~ matches are still case-insensitive under operating systems with case-insensitive filesystems (such as Mac OS & Windows).

To force a case-insensitive pattern you need to include it in the regex itself with (?-i) e.g.

location ~ "(?-i)\.(html)$" {
    ...
}

See this (very old) issue.
