Can anyone confirm this?

TField's Displayformat '###,###,##0.00' displays doubles correctly if
positive, negative numbers are displayed in TDBgrid incorrectly; i.e.
-400 displays as ',-400.00'.

Somehow the determination of whether the rightmost thousand separator
should be shown goes awry when values are negative.

Can you reproduce it with?:
writeln(formatfloat('###,###,##0.00', -400.00));

What type is TField ?
ftFloat, ftBcd or ?

You should use '###,###,##0.00;-###,###,#00.00' as Displayformat

First one is positive number format and the format after ';' is for
negative number .
