It does not seem to be the case. On the other hand it seems to be the case
that the server assigns to text/html twice the quality of text/turtle.

$ http -h https://www.w3.org/ns/prov 'accept:text/turtle,text/html;q=0.5'  
HTTP/1.1 200 OK
content-location: prov.ttl
content-type: text/turtle

$ http -h https://www.w3.org/ns/prov 'accept:text/turtle,text/html;q=0.501'
HTTP/1.1 200 OK
content-location: prov.html
content-type: text/html; charset=utf-8

$ http -h https://www.w3.org/ns/prov accept:text/plain
HTTP/1.1 406 Not Acceptable
alternates: {"prov.html" 1 {type text/html} {length 114463}}, {"prov.rdf" 0.4 {type application/rdf+xml} {length 170917}}, {"prov.ttl" 0.5 {type text/turtle} {length 112777}}, {"prov.xsd" 0.4 {type application/xml} {length 450}}
