Even the most vocal advocate of 8K UHDTV, which is the NHK, recommends a viewing angle of 100 degrees.

SMPTE and THX are not talking about where you should sit (which would appear as implied by your choice of the word "recommended") in the theatre, if that was the case there would be seats in the theatre saying those are the recommended seats that you should use for the best experience. Their specs are for the theatres (room) themselves. And those angles are really for how far the farthest seat in the theatre should be (because if someone sits further then that they are robbed of the big screen experience.)

Now THX has a "recommended" 36 spec and a real max (distance) of 26 for certification but that is for business purposes (i.e. a theater that has a row at 30 will still pass certification and THX will get their$ even it is not within what THX believes to be really acceptable.)
