I wouldn't worry because she is in an inclusion classroom, I would simply worry whether she should have a grade skip.
My sister in law is an autism specialist and she works in an inclusion classroom. Her special ed. training included way more GT info then most regular classroom teachers, so she is an advocate for GT kids (and I think this is true in many states, that special ed. teachers have way more GT training compared to regular teachers). So you may find this works to your advantage. Having the special ed. kids means that the teachers are all more attuned to teaching to the individual kid, as opposed to the group, which is v. helpful for GT kids.
So, don't jump to conclusions. However, if your child is well beyond the K curriculum, that is a different issue (and would be regardless of whether they were in a inclusion classroom or regular K classroom).
