Spectravideo vs. Spectravision

[Room 34]

I received a package today containing a lot of 9 Atari 2600 carts I had won on eBay. I was excited for the new games I was getting, but fairly indifferent to the couple of duplicates. One of those duplicates was Spectravision's Planet Patrol.

 

As I was cleaning the newly-arrived games, however, I noticed that my new copy of Planet Patrol is branded as Spectravideo, not Spectravision. The AA rarity guide makes no indication that the company released its games under both brands, but the Giant List of 2600 Label Variations mentions it.

 

I am just wondering if the carts with one brand name are cosidered rarer than the other.
