On the contrary, for the "dpi" parameter, your logs say:

Something is definitely wrong with the parameter you're passing in here.
Guacamole is continuing to work because it's falling back to its own
default value, being unable to parse the value you've provided.

but when I try to specify the color-depth it not

There will only be a log entry (at the debug level) for values which are
invalid or which are being set to the default value due to being blank. The
value for "color-depth" is not logged when it is specified and a valid
integer. If the parameter is omitted, you would see a log message like:

    guacd[26841]: DEBUG: Parameter "color-depth" omitted. Using default
value of 16.

What version of Windows are you trying to connect to? For the case where
the value you're specifying is not the default color depth of the RDP
server, are you sure that the ability to set the color depth of RDP
connections hasn't been disabled through group policy settings, and that
the RDP server supports that color depth?
