This has been discussed extensively elsewhere but all signs point to this being normal operating temps for the 10R famAs a couple folks correctly recognized, it is the oil temp at 212F, which is perfect, boils off moisture in the oil. The real concern is the trans temp, 205F is 15F higher than I would like to see under normal use.
206-215 has been pretty widely reported as normal observed temps for the 10R80 in the f150, and the ULV ATF specs seem to support this band of temperatures being normal
