In your app you can:

import os
from pathlib import Path
from OpenSSL.crypto import FILETYPE_ASN1
from tlstrust import TrustStore

der = Path(os.path.join(os.path.dirname(__file__), "cacert.der")).read_bytes()
trust_store = TrustStore(FILETYPE_ASN1, der)
print(trust_store.check_trust())

Platform specific checking

all_trusted = trust_store.check_trust()
assert all_trusted is True
assert trust_store.apple # Until December 1st 2021
assert trust_store.android
