About these formats and checking them on a device
"Left out" counts entries a format cannot hold: IP ranges in web filtering, mid-name wildcards, URLs in a V1 domain list, and unfilled values. The V2 JSON is a review format; Microsoft publishes no Graph request shape for V2 rules yet. See how V1 and V2 evaluate.
The same entries are JSON at /api/v1/access-bundles/avd-session-hosts?cloud=USGovGCCHigh. To check them from the workstation itself, run Test-ChangeIntelAccessBundle -Bundle avd-session-hosts -Cloud USGovGCCHigh from the ChangeIntel PowerShell module there: it resolves DNS and tries TCP and TLS to each published host, and reports certificate issuers that suggest TLS inspection.
The profile each destination goes to is inferred from Microsoft's published material, not confirmed. Confirm in the Global Secure Access client: Advanced diagnostics, Forwarding profile.
