This is my Bakeri, it has 2 inflos that look like yours
closeup of leaf blade
compare your inflo to vittariifolium, not a match
also compare to pendulafolium, again no match
I have a wendlingerii, but, its still really a seedling and would be worthless as a comparison just yet. It also does not match A. pallidiflorum.
Hopefully you will get some satisfaction from the seller....but I would not count on it especially if you have had it for a while now. Some people will refuse to admit their mistakes, and blame it (especially on Anthuriums) with 'variability of the species' or 'Its just a juvenile".
If your spadix presents you with thiscenario below, you can be certain its bakeri
