They are both the same 584mm ETRTO diameter. The only difference is that wheels labelled 27.5" are likely, but not certain, to have wider rims. (The same applies to 700C & 29" - the same 622mm ETRTO diameter).

Generally but somewhat confused by the gravel/all road bike trend. My Kona Sutra runs 23mm wide rims, one set of wheels says "29er" on the rims but my tyres all say 700C on the sides.
