But /27s, or anything from /24 through /30 inclusive, won’t include a .0 or .255 host. Only /23s and smaller or /31 and /32 can have hosts with .0 or .255

Are there any publicly advertised, unsummarised /31s or /32s in the global BGP tables?

You are correct:

Only /31s could include .0 and .255 and those would end up on router point to point links.

I filter them out as martians, so I cannot answer this.
