Does X-AspNet-Version correlate to .NET framework version

If a server is reporting its HTTP Headers as:

Server: Microsoft-IIS/10.0
X-SharePointHealthScore: 0
X-AspNet-Version: 4.0.30319

Can this be used to determine if the .NET framework is End of Life. According to Microsoft .NET framework 4.0 is no longer supported.

Apparently not possible from these values. The X-AspNet-Version refers to the common language runtime (CLR) version.

The CLR only translates very roughly to a .NET framework version.

CLR version   .NET version
1.0           1.0
1.1           1.1
2.0           2.0, 3.0, 3.5
4             4, 4.5, 4.6, 4.7, 4.8
