Can the CLI reuse the core platform in Arduino IDE which is already installed?

I installed the arduino:avr core platform for arduion UNO by arduino-cli. And I compared the all files in /Users/AppData/Local/Android15/packages/arduino/hardware directory to all files in /Program Files(x86)/Arduino/hardware which is installed when Arduino IDE is installed. Those are same over 99% except for a little bit different directory structures.
I think it wastes storage. Can the CLI reuse the core platform in Arduino IDE which is already installed?
