Just wanted to follow up on this.
One thing I forgot to mention, is that "mapping" in the tyCache channels rollout refers to mapping overrides on particles. Any map channels on particle shapes themselves will be exported regardless. If you don't see "mapping" in the list of channels in your tyCache loader, it's because tyFlow didn't find any mapping overrides on your particles during export (it strips out unused channels in order to optimize data).
I've tested here with a regular export (no mapping overrides, but shapes with map channels) and the textures displayed normally in the viewport as expected with instancing enabled. So if you run into this issue again (non-override UVWs not displaying properly on tyCaches), let me know.
