Unfortunately I don't think the pictures are enough for anyone to tell.
Also even if the pictures were clear enough it might be that it's just not possible to tell for sure. With clearer pictures it might be possible to get an idea what it's similar to at least.
If it is a hybrid (which I am about 98% sure it is) you will never be able to determine a name for it since a) Dendrobiums are very popular for hybridising so there are potentially hundreds of similar looking hybrids and b) the resulting seedlings from a cross won't all look the same anyway.
