How do I confirm I've compiled in SPIRAM support?

[BetterAutomations]

I have an ESP32-WROVER-IE with 8MB of SPIRAM. How can I confirm that the compilation I did was successful? (Here were the steps I took to build.) I see "Generic ESP32 module with SPIRAM with ESP32" in the bootup message, but that's just a string, and I want to ensure I did it right.

I guess gc.mem_free() and esp32.idf_heap_info() wouldn't show 4+MB if it was not successful, correct?

FYI to anyone who has the same question, it is not currently possible without massive workarounds to use more than 4MB of SPIRAM on a generic ESP32.

print(f"{4183072 / 1024 ** 2:.2f} MiB")

Output: 3.99 MiB

Looks right. You can also test it with x = bytearray(wanted_size),
