but isnt the voom lnb rectange and the dish lnbs flat on one side and rounded on the other

The voom lnb is pretty much equivalent to dish's legacy lnb. Now with this mentioned if you have a dish 500 regardless if they are dp or legacy lnbs you'll use a sw64 switch to bring in either the 61.5 or the 148.
If you have dp lnbs on your dish 500 and wish to use a dp34 switch instead of a sw64 then you'll need to replace the lnb on your voom dish with a dp lnb.
The only way to do that is put the Y-adapter on.
