Is an adapter plate necessary for Samsung 57" G9 with arm mount?

Really just title. I'm very excited to get my 57" to replace my 3 screen setup, but I've never had a 49+ G9 monitor curved monitor before. I'm going to use a desk-mounted gas spring monitor arm like I always use, but I see these $55 adapter plates on Amazon for the G9 for the circular back with the vesa screw holes appearing to be quite recessed?

Just wondering if it's absolutely necessary, or if there's other options? TIA.
