Javascript 在网页性能测试中启用并建议使用Nginx压缩

在chrome开发者工具上，我在网络选项卡上为这个JS文件准备了：

content-type: application/javascript
Request URL: /include/bootstrap/4.5.0/bootstrap.bundle.min.js
accept-encoding: gzip, deflate, br

该服务器是一个已启用压缩的Nginx服务器（Nginx.conf）：

但在一些在线工具上，如我为所有js文件提供的：

Use gzip compression for transferring compressable responses: 69/100Learn More
705.7 KB total in compressible text, target size = 486.2 KB - potential savings = 219.4 KB

FAILED - (79.2 KB, compressed = 21.2 KB - savings of 58.0 KB) - /include/bootstrap/4.5.0/bootstrap.bundle.min.js
FAILED - (87.4 KB, compressed = 30.2 KB - savings of 57.2 KB) - /include/plugins/js/jquery/3.5.1/jquery.min.js

那么，它是压缩的吗？如果是这样的话，为什么它被分析为不被或压缩
