Did I receive the right apple tree?

MM106 is quite a large rootstock. Unless you have quite poor soil or particularly want a large tree, I would stick with M26.

My Red Falstaff is on MM106. Weirdly it is lot less vigorous than the Cevaal on M26. But at my previous house I had Red Falstaff on MM106 and that grew more vigorously so I think it is just this particular one not growing as fast or something about the situation (eg a root from another tree underneath is a possibility, that tree was felled this summer so will see if there is an improvement).

They are both tasty varieties and I like both, just with a slight preference to the Red Falstaff but I couldn't tell you why!
