Not really. VS Code does have some performance optimizations where even the web browser optimization wouldn't suffice, for example it implements its own scroll bar instead of using the web native scroll bar. But for the most part the browser render optimizations is the crucial factor. After years of optimization you can't easily beat a web browser.
Native app is just another set of layers of abstractions. As a comparison, SwiftUI doesn't render 500 items quickly enough (https://www.reddit.com/r/swift/comments/18dlgv0/improving_pe...), which is a tiny number for web.
