It appears that this cable has 8 lanes of DP 1.2 connectivity. 4 DP 1.2 lanes is enough for a non-tiled 4K 60hz display. So TB3 can supply enough bandwidth for two of them. A 5K 60Hz display requires either DP1.3's higher bandwidth lanes or more than 4 DP1.2 lanes teamed in a tiled arrangement. TB3 with DP1.2 will be able to handle single tile 4K displays or double tiled 5K. It will not be able to handle single tile 5K or the other features of DP1.3 (high refresh rate/8K/alternate bit depths)
