Using a proprietary composition engine I'm seeing (or think I'm seeing) the following two fonts are identical.
fontFamily="Yu Gothic UI" fontWeight="Semibold"
fontFamily="Yu Gothic UI" fontWeight="Bold"
Double-checking using Adobe InDesign, these fonts seem identical there too.
There must be some good technical reason for this. Just now I'm scratching my head wondering what it could be ...
I know, not a big issue issue in the scheme of things, but if anyone has any ideas (or corrections) it would be great.
Thank you for the space to ask this question.

By default in InDesign (albeit: depending on preferences settings I think?), that is usually called out by a pink highlight on the text, though, so it is often pretty darn obvious.
Yu Gothic font family - Typography | Microsoft Docs
There are three fonts packed into that ttc file:
- YuGothic-Bold.ttf
- YuGothicUI-Bold.ttf
- YuGothicUI-Semibold.ttf
YuGothicUI-Bold.ttf and YuGothicUI-Semibold.ttf are the same thing indeed. I TTXed both and the only differences are:<head>
<checkSumAdjustment value />
<modified />
<OS/2>
<usWeightClass value />
nameIDs 1, 2, 3, 4, 6, 16 and 17.
For the rest, they are identical.
Folks outside of Microsoft shouldn’t be using the UI fonts anyway as they’re specifically made / modified for the needs of Windows UI, but, well, that ship sailed a long time ago.
FWIW, IMO, Yu Gothic UI has better Latin text for some use cases ...
Okay, so maybe I’m the only person who does that.
