You're arguing a very specific subset, which is a completely different thing than what essentially every article on .NET 6 performance claims. The performance claims are almost always about the whole thing, including various parts of the framework, the standard library and lots of low-level optimizations. Microsoft published an enormously long article detailing many of the optimizations that were done (https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-6/ https://devblogs.microsoft.com/dotnet/performance-improvemen...). And it is not very suprising that pure number-crunching benchmarks only using the .NET IL would not gain very much. As much as I hate to discuss what "real world" applications are, the claims Microsoft and others are focusing on are much more relevant for typical applications where .NET is used than your examples.
