was last Saturdays Notre Dame in Dolby vision or just the "regular HDR"

I now have 2 Xi6 boxes what are DV capable (and enjoyed them both during the Olympics)

I noticed when I tuned into the Notre Dame games, one of my sets was displaying it was receiving a Dolby Vision signal from one of my Xi6 boxes. I did not think these games had Dolby vision so I went into a different room with a different Xi6, and that tv reflected only the HDR 10 4K displayed(no Dolby vision)

important note : BOTH TV's are identical, so it has nothing to go with my TV's and both TV's have "IDENTICAL" setting on them - so we can safely (and smartly) exclude the display as being the reason why.

any Xi6 4K users out there have any ideas?
