I would assume it to be the same as for 3326, which of course doesn’t say either. But doesn’t 3261 make all this sort of thing case-insensitive unless stated otherwise?  7.3.1 says "Unless otherwise stated in the definition of a particular header field, field values, parameter names, and parameter values are case-insensitive.“
