Well not quite.TB3 supports 5k monitors without a problem....so that monitor will work fine with MacBook Pro or any TB3 capable Mac and display at full resolution.
It supports a 5K monitor through 2 DP1.2 MST, the same as having two cables.
Hence why you need to plug two DP cables from the video card into the TB3 adapter for those screen to work.
While yes, macos will show a single screen, it is technically two screens.
You can see it under Windows, the AMD control utility will show them as Screen1 and Screen2, each being half the resolution of the full screen
Same under Linux, which can't join the two screens properly either.
