4k Olympics MIA

No sign of live or on demand 4K UHD Olympics at all. Where is it??? We are now 24 hours after the opening ceremony, and nothing... Searching with remote shows ZERO 4k Olympic content, live or on demand, nothing.... BTW, I have the highest channel package with XG1v4 set to 4k display mode and got the 4k on demand olympics last time around, it was spectacular.

The big announcement says "250 hours of live 4K UHD coverage"... how? where? What channel is 4k? It's NOT my local NBC KCRA3 comcast ch703, so where?
