Don't know if time-delayed. I do know that much is behind a paywall, even the press conferences, also that part of the prize money depends upon the paying cq subscribing public.
The dual GM commentary is pretty OK, engine evaluations on full display too. WC games defy engine analysis though and even a 100 GM's won't be able to fully predict the moves being made. Many moves will be predicted correctly, but as-in most WC matches quite a few will not be accurately anticipated at all.
