Well, I may have to correct my statement: _I_ did not see any change,
except that the format that pvget reports changes.

So my conclusion was that the client (BOY or Display Builder, tried both)
does not handle the format string.
Which is perfectly OK with me if we can agree on a better way than sending
format specifiers. 
And have it implemented, of course (but I think this part of the story is
much shorter).
