I doubt working from home changes all that much. The pattern for most office workloads is still almost all pull. More VoIP is a not insignificant change but it still isn't the same kind of traffic that torrents put down.
Upload is pretty heavy with video chat. However, it's relatively easy to detect from an ISP's standpoint. Almost all the upload will be to a single IP address of a known video conference provider (Zoom, teams, whatever google is doing now, facebook, etc).
