Can Indians really kill deer on the winter range out of season in Region 4?

Yes, Native Americans have a tribal hunting season that is longer than the season established by the State of Idaho. It commonly goes from August through the end of December. They are allowed to hunt on unoccupied federal public lands outside the of the reservation boundaries which does take in at least, portions of IDFG Regions 4, 5, 6, and 7. These hunting rights were established by the Fort Bridger Treaty of 1868.
