I've seen some threads discussing 4k on FIOS on 4K TiVo's like the Bolt+ (what I have). When I go to channel 1498/1499 I see the holding message that shows but it seems to be broadcasting in HD, the info about the "show" says it's HD, and when I find an upcoming program it says it's HD as well. So I guess my question is for those that have gotten 4k content on a TiVo via FIOS, have you actually verified that the signal is 4k (if so, how?) or are you just assuming that because you're getting video content on the 4k channel that it's 4k? I really want to get the Super Bowl in 4k since Verizon has confirmed they're going to have it but I don't want to have to pick up their box to do so.
