Font changes are subject to the fonts installed on your machine.
As far as I know, you get what the system considers the closest match.

Whatever the system has for 14 point is going to look bolder (thicker)
than a smaller sized font.

For me, these fonts:

(set-face-font 'default "DejaVu Sans Mono-12:bold")
(set-face-font 'default "DejaVu Sans Mono-12")

are different, but I have to be careful the order I test in.
I think leaving the font weight unspecified leaves the current
setting unchanged, but I tried using :normal without effect.

(set-face-font 'default "DejaVu Sans 
Mono:bold:foundry=unknown:slant=normal:wieght=normal:height=143:width=normal")

But when I test this, things like the height don't seem to do anything...
Okay I did some testing, in a fresh start Emacs, that does change the
font.  You might want to do:

export FC_DEBUG=1  (or 2)
emacs

then change the fonts.
In the starting terminal you get information about the font matching process.
